PROXY STATEMENT

ANNUAL MEETING OF SHAREHOLDERS

November 17, 2005

      This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of Western Digital Corporation, a Delaware corporation, for use at the Company’s 2005 Annual Meeting of Shareholders to be held on November 17, 2005, at 10:00 a.m., local time, and at any and all adjournments or postponements of the Annual Meeting. The Annual Meeting will be held at The Westin South Coast Plaza located at 686 Anton Boulevard, Costa Mesa, California 92626. This Proxy Statement and the accompanying form of proxy are first being mailed to shareholders on or about October 12, 2005.

VOTING

      September 30, 2005 has been fixed as the record date for the determination of shareholders entitled to notice of and to vote at the Annual Meeting. On the record date, 215,687,733 shares of the Company’s common stock were outstanding. Each share is entitled to one vote on any matter that may be presented for consideration and action by the shareholders at the Annual Meeting. These shares include: (1) shares held directly in your name as the shareholder of record, and (2) shares held for you as the beneficial owner through a stockbroker, trustee or other nominee.

      Most shareholders hold their shares through a broker, trustee or other nominee rather than directly in their own name. If you do hold shares directly in your name with our transfer agent, American Stock Transfer & Trust Company, you are considered the shareholder of record with respect to those shares and these proxy materials are being sent directly to you by the Company. As a shareholder of record, you have the right to grant your voting proxy directly to the named proxy holder or to vote in person at the Annual Meeting. The Company has enclosed a proxy card for you to use. If your shares are held in a brokerage account or by a trustee or other nominee, you are considered the beneficial owner of these shares held in “street name,” and these proxy materials are being forwarded to you together with a voting instruction card. As the beneficial owner, you have the right to direct your broker, trustee or nominee how to vote and are also entitled to attend the Annual Meeting; however, you may not vote these shares in person at the Annual Meeting unless you obtain a “legal proxy” from the broker, trustee or nominee that holds your shares giving you the right to vote the shares in person at the Annual Meeting.

      The holders of a majority of the shares of common stock outstanding on the record date and entitled to vote at the Annual Meeting, present in person or represented by proxy, will constitute a quorum for the transaction of business at the Annual Meeting and any adjournments or postponements thereof. If you submit a properly executed proxy or voting instruction card, even if you abstain from voting, your shares will be counted for purposes of determining the presence or absence of a quorum. If a broker, trustee or other nominee indicates on a proxy that it lacks discretionary authority to vote your shares on a particular matter, commonly referred to as “broker non-votes,” those shares will still be counted for purposes of determining the presence of a quorum at the Annual Meeting.

      Each proxy will be voted FOR election of each of the nine director nominees named in Proposal 1 and FOR each the following three proposals: (1) approval of the Western Digital Corporation 2005 Employee

Stock Purchase Plan, (2) approval of an amendment to the Western Digital Corporation 2004 Performance Incentive Plan, and (3) ratification of the appointment of KPMG LLP as the Company’s independent accountants for the fiscal year ending June 30, 2006, except that if a shareholder has submitted a proxy or voting instruction card with different voting instructions, the shares will be voted according to the shareholder’s direction.

      Any shareholder has the power to revoke his or her proxy or voting instructions at any time before the Annual Meeting. If you are a shareholder of record, you may revoke your proxy by submitting a written notice of revocation to the Secretary of the Company, by submitting a duly executed written proxy bearing a later date to change your vote, or by providing new voting instructions electronically via the Internet or by telephone. A proxy will not be voted if the shareholder of record who executed it is present at the Annual Meeting and votes the shares represented by the proxy in person at the Annual Meeting. For shares you hold beneficially in street name, you may change your vote by submitting new voting instructions to your broker, trustee or nominee, or, if you have obtained a legal proxy from your broker, trustee or nominee giving you the right to vote your shares, by attending the Annual Meeting and voting in person.

      For purposes of Proposal 1, the nine nominees receiving the greatest number of votes represented by shares of the Company’s common stock in person or by proxy and entitled to vote at the Annual Meeting will be elected. Because directors are elected by plurality, abstentions and broker non-votes will be entirely excluded from the vote and will have no effect on the election of directors. Proposals 2, 3 and 4 require the affirmative approval of a majority of the shares present in person or represented by proxy and entitled to vote at the Annual Meeting. For these purposes, abstentions are treated as shares present or represented and entitled to vote at the Annual Meeting, so abstaining has the same effect as a negative vote. However, shares held by brokers, trustees or other nominees who do not have discretionary authority to vote on a particular matter and who have not received voting instructions from their customers are not deemed to be entitled to vote for the purpose of determining whether shareholders have approved that matter and, therefore, will not be counted in determining the outcome of the vote on that matter. If you are a beneficial owner, please note that brokers, trustees and other nominees do not have discretionary authority to vote on your behalf for the adoption of the Western Digital Corporation 2005 Employee Stock Purchase Plan as described in Proposal 2 or the amendment to the Western Digital Corporation 2004 Performance Incentive Plan as described in Proposal 3. As a result, if you do not submit voting instructions to your broker, trustee or other nominee, your shares will not be considered entitled to vote for purposes of determining whether Proposal 2 or Proposal 3 has been approved by shareholders and will not be counted in determining the outcome of Proposal 2 or Proposal 3. All other proposals discussed in this Proxy Statement are considered routine and may be voted upon by your broker, trustee or nominee if you do not give instructions.

SECURITY OWNERSHIP BY PRINCIPAL SHAREHOLDERS AND MANAGEMENT

      The following table sets forth certain information regarding the beneficial ownership of the Company’s common stock, as of September 30, 2005, by (1) each person known by the Company to own beneficially more than 5% of the outstanding shares of the Company’s common stock, (2) each director and each nominee for election as a director of the Company, (3) each of the executive officers named in the Summary Compensation Table below, and (4) all current directors and executive officers as a group. This table is based on information supplied to the Company by the executive officers, directors and principal shareholders or included in a Schedule 13G filed with the Securities and Exchange Commission.

PROPOSAL 1

ELECTION OF DIRECTORS

      The Company’s directors are elected at each Annual Meeting of Shareholders. Currently, the authorized number of directors of the Company is nine. At the Annual Meeting, nine directors will be elected to serve until the next Annual Meeting of Shareholders and until their successors are elected and qualified. The nominees receiving the greatest number of votes at the Annual Meeting up to the number of nine authorized directors will be elected.

Nominees for Election

      The nominees for election as directors set forth below are all incumbent directors. Each of the nominees has consented to serve as a director if elected. If you sign your proxy or voting instruction card but do not give instructions with respect to the voting of directors, your shares will be voted FOR each of the nine persons recommended by the Board. If you wish to give specific instructions with respect to the voting of directors, you may do so by indicating your instructions on your proxy or voting instruction card. In the event that, before the Annual Meeting, any of the nominees for director should become unable to serve if elected, shares represented by proxies will be voted for such substitute nominees as may be recommended by the Company’s existing Board of Directors, unless the Board chooses to reduce the number of directors serving on the Board. To the Company’s knowledge, all the nominees will be available to serve if elected.

Vote Required and Recommendation of the Board of Directors

      The nine persons receiving the greatest number of votes represented by shares of the Company’s common stock in person or by proxy and entitled to vote at the Annual Meeting will be elected.

      THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” ELECTION TO THE BOARD OF DIRECTORS OF EACH OF THE FOLLOWING NOMINEES.

      The following biographical information for each of the nine nominees has been furnished by the nominee:

Corporate Governance

   Corporate Governance Guidelines and Code of Business Ethics. The Board of Directors has adopted Corporate Governance Guidelines, which provide the framework for the governance of the Company and represent the Board’s current views with respect to selected corporate governance issues considered to be of significance to shareholders. The Board of Directors has also adopted a Code of Business Ethics that applies to all of its directors, employees and officers, including, but not limited to, the Chief Executive Officer, the Chief Financial Officer, the Chief Accounting Officer and the Controller of the Company. The current versions of the Corporate Governance Guidelines and the Code of Business Ethics are available on the Company’s website under the Governance section at www.westerndigital.com and are available in print to any shareholder who delivers a written request to the Secretary of the Company at the Company’s principal executive offices. In accordance with rules adopted by the Securities and Exchange Commission and the New York Stock Exchange, the Company intends to disclose future amendments to certain provisions of the Code of Business Ethics, or waivers of such provisions granted to executive officers and directors, on the Company’s website under the Governance section at www.westerndigital.com.

   Director Independence. The Board has reviewed and discussed information provided by the directors and the Company with regard to each director’s business and personal activities as they may relate to the Company or the Company’s management. Based on its review of this information and all other relevant facts and circumstances, the Board of Directors has affirmatively determined that, except for serving as a director of the Company, none of Messrs. Behrendt, DeNero, Kimsey, Lambert, Moore, Pardun or Ms. Cote has any relationship, material or immaterial, with the Company either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company, and that each of such directors qualifies as “independent” as defined by the corporate governance listing standards of the New York Stock Exchange. Mr. Massengill and Mr. Shakeel are both full-time, executive-level employees of the Company; therefore, Mr. Massengill and Mr. Shakeel are not “independent” as defined by the corporate governance listing standards of the New York Stock Exchange.

      The Board of Directors has standing Executive, Audit, Compensation, Governance and Equity Awards Committees. The Governance Committee, among other things, performs functions similar to a nominating committee. The membership of these committees is usually determined at the organizational meeting of the Board held immediately after the annual meeting of shareholders. The current members of the committees are identified in the following table:

      Executive Committee. The Executive Committee operates pursuant to a written charter that is available on the Company’s website under the Governance section at www.westerndigital.com. As described in further detail in the written charter of the Executive Committee, between meetings of the Board, the Executive

Committee may exercise all of the powers of the Board (except those powers expressly reserved to the Board or to another committee by applicable law or the rules and regulations of the Securities and Exchange Commission or the New York Stock Exchange) in the management and direction of the business and conduct of the affairs of the Company, subject to any specific directions given by the Board.

      Audit Committee. The Board of Directors has determined that all members of the Audit Committee are independent as defined under the listing standards of the New York Stock Exchange and applicable rules of the Securities and Exchange Commission and that Mr. DeNero is an “audit committee financial expert” as defined by rules of the Securities and Exchange Commission. The Board has also determined that Mr. Kimsey’s simultaneous service on three other public company audit committees will not impair his ability to effectively serve on the Company’s Audit Committee.

      The Audit Committee operates pursuant to a written charter that is attached as Exhibit A to this Proxy Statement and that is also available on the Company’s website under the Governance section at www.westerndigital.com and is available in print to any shareholder who delivers a written request to the Secretary of the Company at the Company’s principal executive offices. As described in further detail in the written charter of the Audit Committee, the key responsibilities of the Audit Committee include: (1) sole responsibility for the appointment, compensation, retention and oversight of the Company’s independent accountants and, where appropriate, the termination or replacement of the independent accountants; (2) an annual evaluation of the independent accountants’ qualifications, performance and independence, including a review and evaluation of the lead partner; (3) pre-approval of all auditing services and permissible non-auditing services to be performed by the independent accountants; (4) receipt and review of the reports from the independent accountants required annually and prior to the filing of any audit report by the independent accountants; (5) review and discussion with the independent accountants of any difficulties they encounter in the course of their audit work; (6) establishment of policies for the hiring of any current or former employee of the independent accountants; (7) review and discussion with management and the Company’s independent accountants of the Company’s annual and quarterly financial statements prior to their filing or public distribution; (8) general review and discussion with management of the presentation and information to be disclosed in the Company’s earnings press releases; (9) periodic review of the adequacy of the Company’s accounting and financial personnel resources; (10) periodic review and discussion of the Company’s internal control over financial reporting and review and discussion with the Company’s principal internal auditor of the scope and results of the Company’s internal audit program; (11) review and discussion of the Company’s policies with respect to risk assessment and risk management; (12) preparation of the audit committee report included in this Proxy Statement; (13) establishment of procedures for the receipt, retention and treatment of complaints received by the Company regarding accounting, internal accounting controls or auditing matters, and the confidential, anonymous submission of such complaints by Company employees; (14) review of material pending legal proceedings involving the Company and other material contingent liabilities; and (15) review of any other matters relative to the audit of the Company’s accounts and preparation of its financial statements that the Committee deems appropriate.

      Compensation Committee. The Board of Directors has determined that all members of the Compensation Committee are independent as defined under the listing standards of the New York Stock Exchange. The Compensation Committee operates pursuant to a written charter that is available on the Company’s website under the Governance section at www.westerndigital.com and is available in print to any shareholder who delivers a written request to the Secretary of the Company at the Company’s principal executive offices. As described in further detail in the written charter of the Compensation Committee, the Compensation Committee assists the Board of Directors and the Company’s management in defining the Company’s executive compensation policy and in carrying out various responsibilities relating to compensation of the Company’s executive officers and directors, including: (1) evaluating and approving compensation for the Chief Executive Officer and evaluating and recommending to the Board compensation for all other executive officers; (2) reviewing and making recommendations to the Board regarding non-employee director compensation; (3) overseeing the development and administration of the Company’s incentive and equity-based compensation plans, including the Incentive Compensation Plan, the 2004 Performance Incentive Plan, the Deferred Compensation Plan and the 2005 Employee Stock Purchase Plan that is being presented to

shareholders for approval under Proposal 2; and (4) reviewing and making recommendations to the Board regarding changes to the Company’s benefit plans. The Compensation Committee is also responsible for preparing the annual report on executive compensation included in this Proxy Statement.

      Governance Committee. The Board of Directors has determined that all members of the Governance Committee are independent as defined under the listing standards of the New York Stock Exchange. The Governance Committee, which (among other things) performs functions similar to a nominating committee, operates pursuant to a written charter that is available on the Company’s website under the Governance section at www.westerndigital.com and is available in print to any shareholder who delivers a written request to the Secretary of the Company at the Company’s principal executive offices. As described in further detail in the written charter of the Governance Committee, the key responsibilities of the Governance Committee include: (1) evaluating and recommending to the Board the size and composition of the Board and the size, composition and functions of the Board committees; (2) developing and recommending to the Board a set of criteria for Board membership; (3) identifying, evaluating, attracting, and recommending director candidates for membership on the Board, including directors for election at the annual meeting of shareholders; (4) making recommendations to the Board on such matters as the retirement age, tenure and removal of directors; (5) managing the Board performance review process and reviewing the results with the Board on an annual basis; (6) overseeing the evaluation of the Chief Executive Officer by the Board and the Compensation Committee; (7) developing and recommending to the Board a set of corporate governance principles; and (8) reviewing and making recommendations to the Board regarding proposals of shareholders that relate to corporate governance.

      Whenever a vacancy occurs on the Board of Directors, the Governance Committee is responsible for identifying and attracting one or more candidates to fill that vacancy, evaluating each candidate and recommending a candidate for selection by the full Board. In addition, the Governance Committee is responsible for recommending nominees for election or re-election to the Board at each annual meeting of shareholders. The Governance Committee is authorized to use any methods it deems appropriate for identifying candidates for Board membership, including considering recommendations from shareholders. The Governance Committee is authorized to engage outside search firms to identify suitable candidates, but did not engage any third party for this purpose during fiscal 2005.

      While the Governance Committee has no specific minimum qualifications in evaluating a director candidate, the Governance Committee has adopted a policy regarding critical factors to be considered in selecting director nominees which include: the nominee’s personal and professional ethics, integrity and values; the nominee’s intelligence, judgment, foresight, skills, experience (including understanding of marketing, finance, the Company’s technology and other elements relevant to the success of a company such as the Company) and achievements, all of which are viewed in the context of the overall composition of the Board; the absence of any conflict of interest (whether due to a business or personal relationship) or legal impediment to, or restriction on, the nominee serving as a director; having a majority of independent directors on the Board; and representation of the long-term interests of the shareholders as a whole and a diversity of backgrounds and expertise which are most needed and beneficial to the Board and the Company.

      A shareholder may recommend a director candidate to the Governance Committee by delivering a written notice to the Secretary of the Company at the Company’s principal executive offices and including the following in the notice: (1) the name and address of the shareholder as they appear on the Company’s books or other proof of share ownership; (2) the class and number of shares of the Company’s common stock that are beneficially owned by the shareholder as of the date written notice is given; (3) a description of all arrangements or understandings between the shareholder and the director candidate and any other person(s) pursuant to which the recommendation or nomination is to be made by the shareholder; (4) the name, age, business address and residence address of the director candidate and a description of the director candidate’s business experience for at least the previous five years; (5) the principal occupation or employment of the director candidate; (6) the class and number of shares of the Company’s common stock that are beneficially owned by the director candidate; (7) the consent of the director candidate to serve as a director of the Company if elected; and (8) any other information required to be disclosed with respect to such director candidate in solicitations for proxies for the election of directors pursuant to applicable rules of the Securities

and Exchange Commission. The Governance Committee may require additional information as it deems reasonably required to determine the eligibility of the director candidate to serve as a director of the Company.

      The Governance Committee will evaluate director candidates recommended by shareholders for election to the Board of Directors in the same manner and using the same criteria as used for any other director candidate. If the Governance Committee determines that a shareholder-recommended candidate is suitable for Board membership, it will include the candidate in the pool of candidates to be considered for nomination upon the occurrence of the next Board vacancy or in connection with the next annual meeting of shareholders. Shareholders who are recommending candidates for consideration by the Board in connection with the next annual meeting of shareholders should submit their written recommendation no later than June 1 of the year of that meeting.

      Shareholders who wish to nominate a person for election as a director in connection with an annual meeting of shareholders (as opposed to making a recommendation to the Governance Committee as described above) must deliver written notice to the Company’s Secretary within the time periods set forth on page 47 below under “Shareholder Proposals for 2006” and in the manner further described in Section 2.11(a) of the Company’s Bylaws.

      Equity Awards Committee. The Equity Awards Committee was established by the Board of Directors in March 2005 and has been delegated limited authority to approve and establish the terms of stock options and restricted stock awards granted to eligible participants under the 2004 Performance Incentive Plan. Recipients of awards approved by the Equity Awards Committee must be employees on the payroll of the Company or its subsidiaries as of the grant date and generally exclude the Company’s executive and Section 16 officers. The Equity Awards Committee has limited discretion to specify the terms and conditions of awards it approves, subject to guidelines pre-established by the Board of Directors. Further, the number of awards that may be approved by the Equity Awards Committee to any one individual or during any six-month period are subject to maximum limits prescribed by the Board of Directors. The Equity Awards Committee is required to report periodically to the Compensation Committee of the Board of Directors.

   Meetings and Attendance. During fiscal 2005, there were six meetings of the Board, fourteen meetings of the Audit Committee, nine meetings of the Compensation Committee, no meetings of the Executive Committee and four meetings of the Governance Committee. The Equity Awards Committee did not meet or act by written consent during any of fiscal 2005. Each of the directors attended 75% or more of the total number of meetings of the Board and the meetings of the committees of the Board on which he or she served during the period that he or she served.

      The Company strongly encourages each director to attend the Company’s annual meeting of shareholders. All of the Company’s directors attended last year’s annual meeting of shareholders.

   Communicating with Directors. The Board provides a process for shareholders to send communications to the Board, or to individual directors or groups of directors. In addition, interested parties may communicate with the lead director (who presides over executive sessions of the non-management directors) or with the non-management directors as a group. The Board recommends that shareholders and other interested parties initiate any communications with the Board (or individual directors or groups of directors) in writing and send them in care of the Company’s Secretary. These communications should be sent by mail to Raymond M. Bukaty, Secretary, Western Digital Corporation, 20511 Lake Forest Drive, Lake Forest, California 92630-7741. This centralized process will assist the Board in reviewing and responding to shareholder and interested party communications in an appropriate manner. The name of any specific intended Board recipient or recipients should be clearly noted in the communication (including whether the communication is intended only for the Company’s lead director or non-management directors as a group). The Board has instructed the Secretary to forward such correspondence only to the intended recipients; however, the Board has also instructed the Secretary, prior to forwarding any correspondence, to review such correspondence and not to forward any items deemed to be of a purely commercial or frivolous nature (such as spam) or otherwise obviously inappropriate for the intended Board recipient’s consideration. In such cases, some of the correspondence may be forwarded elsewhere within the Company for review and possible response.

Director Compensation

      Director Fees. Non-employee directors receive an annual retainer of $40,000 in January, or if they join the Board at a later date, they receive a proportion of the annual fee corresponding to the period for which they serve. The non-employee directors also receive compensation of $2,500 for each session during which they attend a Board meeting, $1,500 for any and all committee meetings attended, $1,250 for each Board meeting and $750 for each committee meeting held by telephone conference, and reimbursement of reasonable out-of-pocket expenses incurred in attending each meeting. In addition, the chairman of each committee of the Board receives an annual retainer of $5,000. Mr. Massengill and Mr. Shakeel, who are employees of the Company, do not receive any additional compensation for their service on the Board or any Board committee.

      Non-Employee Directors Stock-for-Fees Plan. Under the Company’s Amended and Restated Non-Employee Directors Stock-for-Fees Plan, each non-employee director may elect to receive shares in lieu of any or all of (1) the $40,000 annual retainer fee otherwise payable to him or her in cash for that calendar year, and/or (2) the additional $5,000 chairman retainer, and/or (3) the meeting attendance fees otherwise payable to him or her in cash for that calendar year. At the time of the election for a particular calendar year, a non-employee director may also elect to defer the receipt of any cash or stock compensation to be paid during the calendar year. A deferral will not change the form (cash or shares) in which the fee is to be paid at the end of the deferral period. Under the Deferred Compensation Plan and the Non-Employee Directors Stock-for-Fees Plan, the Company pays a 25% premium to each non-employee director who elects to defer annual retainer or meeting fees to be received in common stock. The number of shares of common stock payable is determined by dividing the amount of the cash fee the director would have received by the fair market value of the common stock on the date the cash fee would have been paid. The aggregate number of shares issued under the Non-Employee Directors Stock-for-Fees Plan in each of the last three fiscal years was: (1) 15,299 shares in fiscal 2005, which includes 13,454 shares of common stock previously deferred under the Deferred Compensation Plan, (2) 3,392 shares in fiscal 2004, and (3) 4,804 shares in fiscal 2003. An aggregate of 164,801 shares representing deferred stock units were credited to accounts in the Company’s Deferred Compensation Plan as of September 30, 2005.

      The maximum aggregate number of shares of the Company’s common stock that may be issued under the Non-Employee Directors Stock-for-Fees Plan is 400,000 shares, subject to adjustments for stock splits and similar events. The Board has the power to suspend, discontinue or, subject to shareholder approval if required by applicable law or regulation, amend the Non-Employee Directors Stock-for-Fees Plan at any time.

      Deferred Compensation Plan. Under the Company’s Deferred Compensation Plan, all directors and employees selected for participation by the Compensation Committee are permitted to defer payment of compensation by the Company. Non-employee directors who elect to participate are permitted to defer between a minimum of $2,000 per calendar year and a maximum of 100% of their compensation payable under the Non-Employee Directors Stock-for-Fees Plan. The deferred stock units carry no voting or investment power. Each participant may elect one or more measurement funds to be used to determine additional amounts to be credited to his or her account balance, including certain mutual funds and a declared rate fund that is credited interest at a fixed rate for each plan year. The fixed interest rate is set prior to the beginning of the plan year. The fixed interest rate for calendar year 2005 is 5.50%, for calendar year 2004 was 6.00%, and for calendar year 2003 was 6.75%.

      Pursuant to the terms of the Deferred Compensation Plan, non-employee directors’ deferred compensation in the last three fiscal years was as follows:

      Non-Employee Director Option Grant Program. Under the Company’s Non-Employee Director Option Grant Program adopted under the Western Digital Corporation 2004 Performance Incentive Plan, non-employee directors are automatically granted an option to purchase 75,000 shares of the Company’s common stock upon initial election or appointment to the Board at an exercise price per share equal to the fair market value of the Company’s common stock on the date of initial election or appointment (“Initial Option”). After a non-employee director joins the Board, immediately following each annual meeting of shareholders of the Company, if he or she has been re-elected as a director at that annual meeting, the non-employee director will automatically receive another option to purchase 10,000 shares of the Company’s common stock at an exercise price per share equal to the fair market value of common stock on the date of grant (“Additional Option”). Both Initial Options and Additional Options vest over a period of four years, with 25% vesting on the first anniversary of the grant date and 6.25% vesting at the end of each three-month period thereafter. Initial Options and Additional Options vest only if the optionee has remained a director for the entire period from the grant date to the vesting date, unless the director retired after reaching age 55, in which case all options immediately vest and shall be exercised by the director before the earlier of (i) three years after the director’s retirement or (ii) the expiration of the original term of the option, provided, in each case, the director has given at least forty-eight months of service to the Company and does not render services to a competitor of the Company. Shares of Company common stock that may be issued upon the exercise of stock options granted under the Non-Employee Director Option Grant Program are subject to the share limits specified in the Company’s 2004 Performance Incentive Plan.

      Non-Employee Directors Restricted Stock Unit Plan. The Company has a Restricted Stock Unit Plan for Non-Employee Directors under which restricted stock units (“RSUs”) are granted to the Company’s non-employee directors. Pursuant to this plan, non-employee directors were granted 2,100 RSUs upon adoption of the plan, 2,100 RSUs each January 1 thereafter through January 1, 2004, and are automatically granted an additional 4,527 RSUs each January 1 beginning January 1, 2005. If a new non-employee director is appointed to the Board, the Company will prorate the first 4,527 RSU grant to the director. All RSUs vest 100% on the third anniversary of the grant. However, if a director served as a director for at least 48 continuous months and is at least 55 years old when such director ceases to be a director (a “Retired Director”), all unvested RSUs vest immediately upon the director’s termination. If a director ceases to be a director for any reason (except removal) prior to becoming eligible to be a Retired Director, then all of the unvested RSUs granted in the first twelve months prior to termination terminate without vesting, 1/3 of all unvested RSUs granted within the

second twelve-month period prior to termination immediately vest and become payable, and 2/3 of all unvested RSUs granted within the third twelve-month period prior to termination immediately vest and become payable. Within 15 days of the vesting of RSUs, the Company will pay the director in cash an amount equal to (i) the product of the number of RSUs vested and (ii) the preceding 45-day average trading price of the Company’s common stock as of the date of vesting. However, the payment amount may not exceed 200% of the value of RSUs on the date of the grant, with the value calculated at the preceding 45-day average trading price on the day of the grant.

EXECUTIVE COMPENSATION

      The following report of the Company’s Compensation Committee addresses the Company’s policies for fiscal 2005 as they affected the Company’s Chief Executive Officer and its other executive officers, including the Named Executive Officers. This report shall not be deemed soliciting material or to be filed with the Securities and Exchange Commission or subject to Regulation 14A or 14C under the Securities Exchange Act or to the liabilities of Section 18 of the Securities Exchange Act, nor shall any information in this report be incorporated by reference into any past or future filing under the Securities Act or the Securities Exchange Act, except to the extent the Company specifically requests that it be treated as soliciting material or specifically incorporates it by reference into a filing under the Securities Act or the Securities Exchange Act.

Report of the Compensation Committee

      The Company’s executive compensation program is administered by the Compensation Committee of the Board of Directors (the “Committee”). The Committee is responsible for recommending to the Board all elements of compensation for executive officers and approving the compensation for the Chief Executive Officer. The Committee also reviews and approves various other Company compensation policies and matters, reviews and makes recommendations to the Board regarding non-employee director compensation, and administers the Company’s equity and incentive plans, including the 2004 Performance Incentive Plan, the Deferred Compensation Plan, the Incentive Compensation Plan and, if approved by shareholders, the 2005 Employee Stock Purchase Plan that is being submitted to shareholders for approval as described in Proposal 2.

      Each member of the Committee is “independent” within the meaning of the applicable listing standards of the New York Stock Exchange. The Committee has the authority to retain such outside counsel, experts and other advisors as it determines appropriate to assist it in the performance of its functions.

      The Company’s compensation philosophy for executive officers is based on the belief that the interests of the executives should be closely aligned with the Company’s shareholders. To support this philosophy, a significant portion of each executive officer’s compensation is placed at risk and linked to the accomplishment of specific results that are expected to lead to the creation of short-term and long-term value for the Company’s shareholders. The Company’s compensation policies and programs are designed to:

      In furtherance of these goals, the Company’s executive compensation policies, plans and programs consist of base salary, annual incentive compensation, long-term retention/incentive awards, including stock options, performance shares and restricted stock grants, a deferred compensation plan and other benefits.

      The Committee considers all elements of compensation and the Company’s compensation philosophy when determining individual components of pay. The Committee does not follow any principles in a formulaic fashion; rather, the members use their experience and judgment in determining the mix of compensation for each individual. In addition to the experience and knowledge of the Committee and the Company’s Human

Resources staff, the Committee utilizes the services of independent human resources consultants who provide advice and counsel, as well as competitive data from independent survey sources of peer companies in competition for similar management talent. The surveys include data from direct competitors of the Company and from other companies in the high-technology industry with similar size and performance characteristics. Most of the companies included in this analysis are also included in the Dow Jones US Technology, Hardware and Equipment Index (see “Stock Performance Graph” at page 25).

      While there is no specific formula that is used to set pay in relation to this market data, executive officer base salary and individual bonus target amounts, when combined, are generally equivalent to the median total cash compensation level for comparable jobs in the marketplace. However, depending upon the Company’s business groups’ performance as measured against predetermined financial and non-financial goals, amounts paid under the Company’s performance-based compensation program may lead to total cash compensation levels that are lower or higher than the median levels for comparable jobs. The Company intends to provide a total compensation opportunity for executive officers that is above average, but with an above-average amount of the total compensation opportunity at risk and dependent upon Company performance.

      The Company’s executive compensation package consists primarily of the following components:

      Base Salary. Executive officer base salaries are reviewed annually, and base salary levels are generally targeted at or below the median of competitive data. The base salaries of individual executive officers can and do vary from this salary benchmark based on such factors as the competitive environment, the executive’s experience level and scope of responsibility, the Company’s financial condition, current performance, future potential and the overall contribution of the executive. The Committee exercises its judgment based on all the factors described above in making its decisions. No specific formula is applied to determine the weight of each criterion.

      Annual Incentive Compensation. The Company’s Incentive Compensation Plan (the “ICP”) formally links cash bonuses for executive officers and other participating employees to the Company’s semiannual operating performance. The Committee establishes target awards under the ICP for each executive officer, expressed as a percentage of the executive’s semiannual base salary. The Committee then semiannually establishes operating and/or financial performance goals under the ICP. For each of the first half and second half of fiscal 2005 these goals were earnings per share (EPS) and cash flow from operations. The bonus pool payable under the ICP for each semiannual period can vary from 0% to 200% of the aggregate target bonuses, depending upon the Company’s performance against the pre-established goals. Individual awards to executive officers can also vary from their targets, depending upon the size of the bonus pool and their individual performance.

      Equity and Other Long-Term Incentive Awards. The Committee views the grant of equity-based compensation to be a key long-term incentive reward program. Executive officers, as well as other employees, are eligible to receive periodic grants of incentive stock options and non-qualified stock options, restricted stock, performance shares and other cash or equity-based incentive awards pursuant to the Company’s 2004 Performance Incentive Plan. Vesting schedules are designed to balance the goals of encouraging retention of executive officers and rewarding long-term performance and commitment to the Company. While all executive officers are eligible, the type of award as well as the size of the grant each executive officer receives, is determined by the Committee in consultation with the Vice President, Human Resources and the Chief Executive Officer (except in the case of his own equity and other long-term incentive awards), and ratified by the Board. In the case of the Chief Executive Officer’s compensation, any and all awards are approved by the Committee.

      The amount of each executive officer’s award is determined by the Committee based upon the executive’s individual performance, the executive’s current compensation package, the value of the executive’s unvested stock options and restricted stock, comparable company and competitive company practices, and the Committee’s appraisal of the executive’s anticipated long-term future contribution to the Company.

      Benefits. Benefits offered to executive officers serve a different purpose than do the other elements of total compensation. In general, they provide a safety net of protection against the financial catastrophes that can result from illness, disability or death. Benefits offered to executives are largely those that are offered to the general employee population, with some variation, primarily with respect to eligibility for participation in the non-qualified deferred compensation plan, the availability of expanded medical benefits, and the availability of various limited allowances, including life insurance, financial planning and club memberships. The Committee believes that the benefits offered to executive officers generally are competitive. From time to time, the Company’s Human Resources Department obtains data to help ensure that such benefit plans and programs remain competitive and reports its findings to the Committee.

      The Committee believes that the Company delivered exceptional financial performance during fiscal 2005, and as a result the value of the Company’s common stock rose from $8.40 on July 2, 2004 to $13.76 on July 1, 2005. This exceptional financial performance is highlighted by:

      Because the Company exceeded all of the financial and other performance goals under the ICP in fiscal 2005, ICP cash awards equivalent to approximately 150% of the target awards were made to executive officers for the six months ended December 31, 2004 and ICP cash awards equivalent to approximately 175% of the target awards were made to executive officers for the six months ended July 1, 2005.

      Historically, the Company has granted stock options with an exercise price equal to the fair market value per share of the Company’s common stock on the date of grant as its primary long-term retention vehicle. With the assistance of outside compensation consultants during the fiscal year, the Committee developed an annual equity award package that focused on certain long-term financial objectives and consisted of stock options, restricted stock and performance shares.

      The stock options, restricted stock awards and performance shares granted to the Named Executive Officers in fiscal 2005 are summarized below under “Summary Compensation,” “Option/ SAR Grants in Last Fiscal Year” and “Long-Term Incentive Plans — Awards in Last Fiscal Year” beginning at page 24.

      In addition, in fiscal 2005, Dr. Moghadam received a long-term incentive award payable in cash upon the satisfaction of specified time-based vesting requirements. The Long-Term Retention Agreement documenting this award is described in further detail under “Employment Contracts, Termination of Employment and Change-in-Control Arrangements” beginning on page 26.

      Mr. Massengill was appointed Chief Executive Officer of the Company in January 2000 and Chairman of the Board of Directors in November 2001. His compensation package has been designed to encourage both short-term and long-term performance of the Company as well as to align his interests with the interests of shareholders. The majority of his compensation, including stock options and other stock-based compensation, annual incentive bonuses and long-term retention awards, is at risk and ultimately based upon the financial performance of the Company. During fiscal 2005, Mr. Massengill did not have an employment contract, but he was and remains subject to the Company’s Change of Control Severance Plan and was party to a Long-Term Retention Agreement (both of which are described in “Employment Contracts, Termination of Employment and Change-in-Control Arrangements” beginning on page 26).

      The Committee reviews and approves corporate goals and objectives for the compensation of the Chief Executive Officer, evaluates the Chief Executive Officer’s performance in light of those goals and objectives and, either as a Committee or together with the other independent directors of the Board, determines and approves the Chief Executive Officer’s compensation level. On behalf of the Board, the Governance Committee will, as it and the Committee determine appropriate, provide input to the Committee on the performance of the Chief Executive Officer. The Company’s overall performance and Mr. Massengill’s individual performance are critical factors in the Committee’s determination.

      Mr. Massengill’s annual base salary at the end of fiscal 2005 was $800,000, paid bi-weekly. The incentive compensation plan awards paid to Mr. Massengill for fiscal 2005 totaled $1,300,000. During fiscal 2005, he received a stock option grant to purchase 500,000 shares of the Company’s common stock, which vests 25% on the first anniversary of the grant date and 6.25% at the end of each three-month period thereafter through the fourth anniversary of the grant date. During fiscal 2005, Mr. Massengill also received 550,000 shares of restricted stock. A total of 400,000 of these shares vest 50% on July 31, 2006 and 50% on July 31, 2007, while the remaining 150,000 shares vest in equal installments on each of July 31, 2006, 2007 and 2008. Finally, Mr. Massengill received an award of 210,000 performance share units. In addition, on July 1, 2005, the final annual installment representing 45% of the total “share units” awarded to Mr. Massengill in fiscal 2003 pursuant to his Long-Term Retention Agreement vested, resulting in a cash payment to him of $5,808,600.

      The Committee’s decisions regarding the award of stock options, restricted stock and performance share units to Mr. Massengill during fiscal 2005 were based on its positive assessment of his performance and in recognition of his leadership of the Company’s exceptional financial success.

      On August 25, 2005, Mr. Massengill entered into an Employment Agreement with the Company pursuant to which he relinquished his role as Chief Executive Officer of the Company effective October 1, 2005. Mr. Massengill will still remain a full-time employee of the Company in his position as Chairman of the Board of Directors. Pursuant to his agreement, the entire performance share award granted to Mr. Massengill in fiscal 2005 was cancelled as were 50,000 unvested shares of restricted stock and an aggregate of

206,250 shares of common stock subject to stock options granted to Mr. Massengill that were scheduled to vest after July 31, 2007.

      Effective October 1, 2005, the Board of Directors appointed Mr. Shakeel to replace Mr. Massengill as Chief Executive Officer of the Company. Pursuant to an Employment Agreement entered into with Mr. Shakeel on August 25, 2005, effective October 1, 2005, Mr. Shakeel’s base salary increased to $800,000 and his target annual bonus under the ICP will be 100% of his base salary. Mr. Shakeel also received an award grant of 1,250,000 shares of restricted stock of the Company. Subject to Mr. Shakeel’s continued employment by the Company, 500,000 of these shares of restricted stock will vest on January 1, 2007 and the remaining 750,000 of these shares of restricted stock will vest on January 1, 2008. In addition, pursuant to the agreement, the entire performance share award granted to Mr. Shakeel in fiscal 2005 was cancelled as were 28,333 unvested shares of restricted stock and 78,125 shares of common stock subject to stock options granted to Mr. Shakeel that were scheduled to vest after December 31, 2007.

      Section 162(m) of the Internal Revenue Code, enacted in 1993, generally disallows a tax deduction to public companies for compensation in excess of $1 million paid to the Company’s Chief Executive Officer or any of the Company’s four other most highly compensated executive officers as of the end of any fiscal year. Certain performance-based compensation, however, is exempt from the Section 162(m) deduction limit. It is the Committee’s current intent that, so long as it is consistent with the Company’s overall compensation objectives and philosophy, executive compensation will be structured so as to be deductible for federal income tax purposes to the maximum extent possible. The 2004 Performance Incentive Plan has been structured so that any taxable compensation derived pursuant to the exercise of options approved by the Committee and granted under such plans should not be subject to the Section 162(m) deductibility limitations. In addition, the Company’s 2005 performance share grants to executive officers are intended to be exempt from the Section 162(m) deductibility limitations. Base salaries, bonuses under the ICP, cash awards and restricted stock awards under the executive retention program do not, however, satisfy all the requirements of Section 162(m) and, accordingly, are not exempt from the Section 162(m) deductibility limitations. Nevertheless, the Committee has determined that these plans and policies are in the best interests of the Company and its shareholders since the plans and policies permit the Company to recognize an executive officer’s contributions as appropriate. The Committee will, however, continue to consider, among other relevant factors, the deductibility of compensation when the Committee reviews the Company’s compensation plans and policies. The Committee reserves the right to continue to award non-deductible compensation in such circumstances as it deems appropriate.

Summary Compensation Table

      The following table sets forth the compensation paid for fiscal 2005 to the Company’s Chief Executive Officer during that period and the four other most highly compensated executive officers who were serving as executive officers at the end of fiscal 2005 (collectively, the “Named Executive Officers”).

Option/ SAR Grants in Last Fiscal Year

      The following table sets forth information regarding stock options to purchase shares of the Company’s common stock granted to the Named Executive Officers during fiscal 2005 and the potential realizable value at certain assumed rates of stock price appreciation for the option term. These assumed rates are in accordance with the rules of the Securities and Exchange Commission and do not represent the Company’s estimate of future stock price. Actual gains, if any, on stock option exercises will be dependent on the future performance of the Company’s common stock.

Aggregated Option/ SAR Exercises in Last Fiscal Year and Fiscal Year-End Option/ SAR Values

      The following table sets forth the option exercises in fiscal 2005, the number of shares covered by exercisable and unexercisable options held by the Named Executive Officers on July 1, 2005, and the aggregate gains that would have been realized had these options been exercised on July 1, 2005 even though these options were not exercised, and the unexercisable options could not have been exercised, on July 1, 2005.

Long-Term Incentive Plans — Awards in Last Fiscal Year

      The following table sets forth the number of performance shares granted to the Named Executive Officers during fiscal 2005. Each performance share award was granted under the 2004 Performance Incentive Plan and provides for a target number of shares that will be payable if certain performance conditions are satisfied. No shares will be payable if minimum performance levels are not achieved. Up to a maximum of 300% of the target number of shares will be paid if performance exceeds the target level.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

      The Compensation Committee consists of Messrs. Behrendt, Lambert and Moore. No member of the Compensation Committee during fiscal 2005 was a current or former officer or employee of the Company. There are no Compensation Committee interlocks between the Company and other entities in which an executive officer of the Company served on the compensation committee (or equivalent) of the board of directors of another entity whose executive officer(s) served on the Company’s Compensation Committee or Board of Directors.

STOCK PERFORMANCE GRAPH

      The following graph compares the cumulative total shareholder return of the Company’s common stock with the cumulative total return of the S&P 500 Index and the Dow Jones US Technology, Hardware and Equipment Index for the five years ended July 1, 2005. The graph assumes that $100 was invested on June 30, 2000 in the Company’s common stock and each index and that all dividends were reinvested. No cash dividends have been declared on the Company’s common stock. Shareholder returns over the indicated period should not be considered indicative of future shareholder returns.

      The stock performance graph shall not be deemed soliciting material or to be filed with the Securities and Exchange Commission or subject to Regulation 14A or 14C under the Securities Exchange Act or to the liabilities of Section 18 of the Securities Exchange Act, nor shall it be incorporated by reference into any past or future filing under the Securities Act or the Securities Exchange Act, except to the extent the Company specifically requests that it be treated as soliciting material or specifically incorporates it by reference into a filing under the Securities Act or the Securities Exchange Act.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

      Under the securities laws of the United States, the directors and officers of the Company and persons who beneficially own more than 10% of the Company’s common stock are required to report their initial ownership of the Company’s equity securities and any subsequent changes in that ownership to the Securities and Exchange Commission and the New York Stock Exchange. Specific due dates for these reports have been established, and the Company is required to disclose in this Proxy Statement any late filings during fiscal 2005. To the Company’s knowledge, based solely on its review of the copies of such reports required to be furnished to the Company with respect to fiscal 2005 and the written responses to annual directors and officers

questionnaires that no other reports were required, all of these reports were timely filed, except for one Form 4 for one of our directors, Thomas E. Pardun, that was filed to report the disposition and reacquisition of 5,000 shares traded contrary to limited discretionary authority by his investment manager.

EMPLOYMENT CONTRACTS, TERMINATION OF EMPLOYMENT AND

CHANGE-IN-CONTROL ARRANGEMENTS

Employment Arrangements

      Mr. Massengill. On August 25, 2005, the Company entered into an Employment Agreement with Mr. Massengill pursuant to which he relinquished the role of Chief Executive Officer of the Company, effective October 1, 2005, and agreed to continue to serve as Chairman of the Board of Directors or in such other executive capacity as may be assigned by the Board. Mr. Massengill’s duties as Chairman of the Board will include offering assistance to Mr. Shakeel in his new position as Chief Executive Officer and coordinating investor communications.

      In accordance with the agreement, Mr. Massengill will continue to receive base salary at his current annual rate of $800,000, his target annual bonus under the Company’s Incentive Compensation Plan will be 100% of his base salary, and Mr. Massengill will be entitled to participate in the Company’s other benefit plans on terms consistent with those generally applicable to the Company’s other senior executives. Mr. Massengill’s outstanding stock options and shares of restricted stock, to the extent that such options and shares of restricted stock were scheduled to vest after July 31, 2007, have been cancelled pursuant to the agreement. Provided that Mr. Massengill remains employed by the Company through January 1, 2007, any of his outstanding stock options and any of his shares of restricted stock that are scheduled to vest after January 1, 2007 and on or before July 31, 2007 will accelerate and become vested on January 1, 2007. With respect to the accelerated options, Mr. Massengill will have until the later of (i) January 1, 2010, or (ii) the time the options would have otherwise expired or been terminated in accordance with the termination of employment rules otherwise applicable to the options (but in no event later than the expiration date of the options) to exercise the options. Also pursuant to the agreement, the entire performance share award granted to Mr. Massengill in January 2005, as further described under “Executive Compensation — Long-Term Incentive Plans — Awards in Last Fiscal Year” on page 24, has been cancelled.

      If the Company terminates Mr. Massengill’s employment other than for cause (as defined in the agreement) prior to January 1, 2007, Mr. Massengill will be entitled to (i) a lump sum cash payment equal to his base salary and target bonus for the period between the date his employment terminates and January 1, 2007, and (ii) accelerated vesting of any and all options and other equity-based awards granted by the Company that are then outstanding and not otherwise fully vested, but only to the extent such awards were otherwise scheduled to vest on or before July 31, 2007. The Employment Agreement with Mr. Massengill expires January 1, 2007, subject to certain termination provisions.

      Mr. Shakeel. On August 25, 2005, the Company also entered into an Employment Agreement with Mr. Shakeel pursuant to which he became the Chief Executive Officer and President of the Company, effective October 1, 2005. In accordance with the agreement, effective October 1, 2005, Mr. Shakeel’s annual base salary increased to $800,000, his target annual bonus under the Company’s Incentive Compensation Plan will be 100% of his base salary, and Mr. Shakeel will be entitled to participate in the Company’s other benefit plans on terms consistent with those generally applicable to the Company’s other senior executives. In addition, pursuant to the agreement, Mr. Shakeel was granted an award of 1,250,000 shares of restricted stock of the Company. Subject to Mr. Shakeel’s continued employment by the Company, 500,000 of these restricted shares will vest on January 1, 2007, and the remaining 750,000 of these shares of restricted stock will vest on January 1, 2008.

      Mr. Shakeel’s outstanding stock options and shares of restricted stock, to the extent that such options and shares of restricted stock were scheduled to vest after December 31, 2007, have been cancelled pursuant to the agreement. Also pursuant to the agreement, the entire performance share award granted to Mr. Shakeel in

January 2005, as further described under “Executive Compensation — Long-Term Incentive Plans — Awards in Last Fiscal Year” on page 24, has been cancelled.

      If the Company terminates Mr. Shakeel’s employment other than for cause (as defined in the agreement) prior to January 1, 2008, Mr. Shakeel will be entitled to (i) a lump sum cash payment equal to his base salary and target bonus for the period between the date his employment terminates and January 1, 2008, and (ii) accelerated vesting of any and all options and other equity-based awards granted by the Company that are then outstanding and not otherwise fully vested, but only to the extent such awards were otherwise scheduled to vest before January 1, 2008. The Employment Agreement with Mr. Shakeel expires January 1, 2008, subject to certain termination provisions.

      Mr. Milligan. The Company entered into an agreement with Mr. Milligan, dated September 10, 2004, relating to his employment with the Company. Pursuant to the agreement, Mr. Milligan is eligible to receive a retention bonus of $35,000 payable upon completion of twenty-four months of employment at the Company. The bonus is repayable by Mr. Milligan to the Company if, within six months after the payment date, his employment is voluntarily terminated or terminated for “good cause” as defined in the agreement.

Long-Term Retention Agreements

      Mr. Massengill and Mr. Shakeel. The Company entered into Amended and Restated Long-Term Retention Agreements with each of Mr. Massengill and Mr. Shakeel, effective December 20, 2002, amending and restating prior long-term retention agreements with each of them. The Long-Term Retention Agreements were intended to add incentives for the executives to advance the long-term interests of the Company. Pursuant to the Long-Term Retention Agreements, Mr. Massengill and Mr. Shakeel were granted 1.4 million and 1.0 million “share units,” respectively, subject to certain adjustment, vesting, forfeiture and repayment provisions. The share units vested in three installments: 25% vested on July 1, 2003, 30% vested on July 1, 2004 and 45% vested on July 1, 2005. Within fifteen days of each vesting period, the Company paid each executive a cash amount equal to the product of the number of share units vesting and the average closing price of the Company’s common stock for the preceding forty-five day period, but in no event more than $9.22 per share unit. The “share units” granted to each of the executives have fully vested and, therefore, no further payments will be made to Mr. Massengill or Mr. Shakeel pursuant to these agreements. The amounts paid to each executive are further detailed under “Executive Compensation — Summary Compensation Table” on page 19.

      Dr. Moghadam. The Company entered into a Long-Term Retention Agreement with Dr. Moghadam, effective September 21, 2004, for the purpose of giving Dr. Moghadam an added incentive to advance the interests of the Company. Pursuant to this agreement, Dr. Moghadam was granted a cash award in the amount of $450,000 that vested and became payable 25% on September 1, 2005 and will vest and become payable 30% on September 1, 2006 and 45% on September 1, 2007, subject to Dr. Moghadam’s continued employment with the Company. In the event of certain corporate changes (as described in the agreement and including the Company’s liquidation or a merger, reorganization or consolidation of the Company with another company in which the Company is not the surviving corporation and the surviving corporation does not assume the award or agree to issue a substitute award in its place) or the termination of Dr. Moghadam’s employment upon a Change of Control (as defined in the agreement), any unvested portion of the cash award will vest in full and be payable to Dr. Moghadam. Further, in the event that Dr. Moghadam’s employment with the Company terminates due to his death, the next installment of the cash award scheduled to vest will immediately vest and became payable to Dr. Moghadam and all other unvested portions of the cash award will be forfeited.

Change of Control Severance Plan

      Effective March 29, 2001, the Company’s Board of Directors adopted a Change of Control Severance Plan covering certain executives of the Company and its subsidiaries, including each of the currently employed Named Executive Officers. The Change of Control Severance Plan provides for payment of severance benefits to each participating executive officer in the event of termination of his or her employment in connection with

a change of control of the Company. The plan provides for two levels of severance benefits. The severance benefits are payable if the Company and its subsidiaries terminate the employment of the executive officer without cause or the employee voluntarily terminates his or her employment for good reason (generally consisting of adverse changes in responsibilities, compensation, benefits or location of work place, or breach of the plan by the Company or any successor) within one year after a change of control or prior to and in connection with, or in anticipation of, such a change. The plan is effective until March 29, 2006, and may be extended by the Board of Directors until March 29, 2011.

      For each of the Named Executive Officers and other officers of the Company subject to Section 16 of the Securities Exchange Act, the severance benefits generally consist of the following:

      Any health and welfare benefits will be reduced to the extent of the receipt of substantially equivalent coverage by the officer from any successor employer. Generally, the benefits will be increased to the extent the officer has to pay taxes associated with “excess parachute payments” under the Internal Revenue Code, such that the net amount received by the officer is equal to the total payments he or she would have received had the tax not been incurred.

Stock Incentive Plans and Deferred Compensation Plan

      Subject to certain conditions or restrictions as described in the Company’s stock incentive plans, the Company’s stock incentive plans generally provide for the acceleration of the vesting of awards granted thereunder in the event of certain change of control events described in the plans. In these circumstances, each option may become immediately exercisable, restricted stock may immediately vest and the number of shares covered by each performance share award may be issued to the participant. Further, under the Company’s Deferred Compensation Plan, in the event of certain change of control events described in the plan, Company contribution amounts and deferral amounts will immediately vest (to the extent unvested) and will become payable to participants as provided in the plan.

PROPOSAL 2

APPROVAL OF THE WESTERN DIGITAL CORPORATION

2005 EMPLOYEE STOCK PURCHASE PLAN

      At the Annual Meeting, shareholders will be asked to approve the Western Digital Corporation 2005 Employee Stock Purchase Plan, which was adopted, subject to shareholder approval, by the Board of Directors on September 20, 2005. If shareholders approve the 2005 Employee Stock Purchase Plan, the Western Digital Corporation 1993 Employee Stock Purchase Plan, which was suspended by the Company on July 21, 2005 with respect to future exercise periods, will be terminated.

      Under the 2005 Employee Stock Purchase Plan, shares of the Company’s common stock will be available for purchase by eligible employees who elect to participate in the 2005 Employee Stock Purchase Plan. Eligible employees will be entitled to purchase, by means of payroll deductions, limited amounts of the Company’s common stock at a discount during periodic offering periods. Subject to the requirements described below, the Company will establish in advance of each offering period the duration of the offering period and the methodology for determining the purchase price of the shares to be offered during the offering period. The 2005 Employee Stock Purchase Plan will not be effective without shareholder approval.

      The Board of Directors believes that the 2005 Employee Stock Purchase Plan will help the Company retain and motivate eligible employees and will help further align the interests of eligible employees with those of the Company’s shareholders.

Summary Description of the 2005 Employee Stock Purchase Plan

      The principal terms of the 2005 Employee Stock Purchase Plan are summarized below. The following summary is qualified in its entirety by the full text of the 2005 Employee Stock Purchase Plan, which appears as Exhibit B to this Proxy Statement.

      Purpose. The purpose of the 2005 Employee Stock Purchase Plan is to provide eligible employees with an opportunity to purchase shares of the Company’s common stock at a favorable price and upon favorable terms in consideration of the participating employees’ continued services. The 2005 Employee Stock Purchase Plan is intended to provide an additional incentive to participating eligible employees to remain in the Company’s employ and to advance the best interests of the Company and its shareholders.

      Operation of the 2005 Employee Stock Purchase Plan. The 2005 Employee Stock Purchase Plan will operate in a series of periods referred to as “Offering Periods.” If shareholders approve the 2005 Employee Stock Purchase Plan, the Company currently expects that the first Offering Period will commence on December 1, 2005. The Company will establish the duration of each Offering Period in advance of that Offering Period. However, an Offering Period may not be longer than 24 months. The Company may provide for a new Offering Period to start before an Offering Period in progress has ended, but no one participant may participate in more than one Offering Period at the same time.

      On the first day of each Offering Period (referred to as the “Enrollment Date”), each eligible employee who has timely filed a valid election to participate in the 2005 Employee Stock Purchase Plan for that Offering Period will be granted an option to purchase shares of the Company’s common stock. A participant may designate in his or her election the percentage of his or her compensation to be withheld from his or her pay during that Offering Period for the purchase of stock under the 2005 Employee Stock Purchase Plan. The participant’s contributions under the 2005 Employee Stock Purchase Plan will be credited to a bookkeeping account in his or her name. A participant generally may elect to terminate his or her contributions to the 2005 Employee Stock Purchase Plan at any time during an Offering Period. A participant also generally may elect to increase or decrease the rate of his or her contributions to the 2005 Employee Stock Purchase Plan up to four times in a calendar year. Amounts contributed to the 2005 Employee Stock Purchase Plan constitute general corporate assets of the Company and may be used for any corporate purpose.

      An Offering Period may consist of one or more periods referred to as “Exercise Periods.” The last day of each Exercise Period is referred to as an “Exercise Date.” Each option granted under the 2005 Employee

Stock Purchase Plan for an Offering Period will automatically be exercised on each Exercise Date that occurs within that Offering Period. The number of shares acquired by a participant upon exercise of his or her option will be determined by dividing the participant’s account balance under the 2005 Employee Stock Purchase Plan as of the Exercise Date by the Exercise Price for that Offering Period. The Company will establish the methodology for setting the Exercise Price in an Offering Period in advance of that Offering Period, except that in no event may the Exercise Price be lower than the lesser of (i) 85% of the fair market value of a share of the Company’s common stock on the applicable Enrollment Date, or (ii) 85% of the fair market value of a share of the Company’s common stock on the applicable Exercise Date. A participant’s account will be reduced upon exercise of his or her option by the amount used to pay the Exercise Price of the shares acquired by the participant. No interest will be paid to any participant or credited to any account under the 2005 Employee Stock Purchase Plan.

      Eligibility. Only certain employees will be eligible to participate in the 2005 Employee Stock Purchase Plan. To be eligible to participate in an Offering Period, on the Enrollment Date of that period an individual must:

      As of July 1, 2005, approximately 23,161 employees of the Company and its subsidiaries, including all of the Named Executive Officers, would have been eligible to participate in the 2005 Employee Stock Purchase Plan had the plan then been in effect.

      Limits on Authorized Shares; Limits on Contributions. If shareholders approve the 2005 Employee Stock Purchase Plan, a maximum of 5,000,000 shares of the Company’s common stock will be available for delivery under the plan.

      Participation in the 2005 Employee Stock Purchase Plan is also subject to the following limits:

      The Company has the flexibility to change the 10%-contribution referred to above and to fix a maximum limit on the number of shares that may be acquired by any individual during an Exercise Period under the 2005 Employee Stock Purchase Plan from time to time without shareholder approval. However, the Company cannot increase the aggregate share limit under the 2005 Employee Stock Purchase Plan without shareholder approval, other than to reflect stock splits and similar adjustments as described below. The $25,000 and the 5% ownership limitations referred to above are required under the Code.

      Antidilution Adjustments. As is customary in stock incentive plans of this nature, the number and kind of shares available under the 2005 Employee Stock Purchase Plan, as well as purchase prices and share limits under the 2005 Employee Stock Purchase Plan, are subject to adjustment in the case of certain corporate events. These events include reorganizations, mergers, combinations, consolidations, recapitalizations, reclassifications, stock splits, stock dividends, asset sales or other similar unusual or extraordinary corporate events, or extraordinary dividends or distributions of property to the Company’s shareholders.

      Termination of Participation. A participant’s election to participate in the 2005 Employee Stock Purchase Plan will generally continue in effect for all Offering Periods until the participant files a new election that takes effect or the participant ceases to participate in the 2005 Employee Stock Purchase Plan. A participant’s participation in the 2005 Employee Stock Purchase Plan generally will terminate if, prior to the applicable Exercise Date, the participant ceases to be employed by the Company or one of its participating subsidiaries or the participant is no longer scheduled to work more than 20 hours per week.

      If a participant’s participation in the 2005 Employee Stock Purchase Plan terminates during an Offering Period for any of the reasons discussed in the preceding paragraph, he or she will no longer be permitted to make contributions to the 2005 Employee Stock Purchase Plan for that Offering Period and, subject to limited exceptions, his or her option for that Offering Period will automatically terminate and his or her account balance will be paid to him or her in cash without interest. However, a participant’s termination from participation will not have any effect upon his or her ability to participate in any succeeding Offering Period, provided that the applicable eligibility and participation requirements are again then met.

      Transfer Restrictions. A participant’s rights with respect to options or the purchase of shares under the 2005 Employee Stock Purchase Plan, as well as contributions credited to his or her account, may not be assigned, transferred, pledged or otherwise disposed of in any way except by will or the laws of descent and distribution.

      Administration. The 2005 Employee Stock Purchase Plan is administered by the Board of Directors or by a committee appointed by the Board of Directors. The Board of Directors has appointed the Compensation Committee of the Board of Directors as the current administrator of the 2005 Employee Stock Purchase Plan. The administrator has full power and discretion to adopt, amend or rescind any rules and regulations for carrying out the 2005 Employee Stock Purchase Plan and to construe and interpret the 2005 Employee Stock Purchase Plan. Decisions of the administrator with respect to the 2005 Employee Stock Purchase Plan are final and binding on all persons.

      No Limit on Other Plans. The 2005 Employee Stock Purchase Plan does not limit the ability of the Board of Directors or any committee of the Board of Directors to grant awards or authorize any other compensation, with or without reference to the Company’s common stock, under any other plan or authority.

      Amendments. The Board of Directors generally may amend or suspend the 2005 Employee Stock Purchase Plan at any time and in any manner. No amendment, suspension or termination of the 2005 Employee Stock Purchase Plan may have a material adverse effect on the then-existing rights of any participant during an Exercise Period without the participant’s written consent, but the Board of Directors may amend, suspend or terminate the 2005 Employee Stock Purchase Plan as to any outstanding options granted under the 2005 Employee Stock Purchase Plan for an Offering Period, effective as of any Exercise Date within that Offering Period, without the consent of the participants to whom such options were granted. Shareholder approval for an amendment to the 2005 Employee Stock Purchase Plan will only be required to the extent necessary to meet the requirements of Section 423 of the Code or to the extent otherwise required by law or applicable stock exchange rules.

      Termination. The Board of Directors may terminate the 2005 Employee Stock Purchase Plan at any time. The 2005 Employee Stock Purchase Plan will also terminate earlier if all of the shares authorized under the 2005 Employee Stock Purchase Plan have been purchased.

Federal Income Tax Consequences of the 2005 Employee Stock Purchase Plan

      Following is a general summary of the current federal income tax principles applicable to the 2005 Employee Stock Purchase Plan. The following summary is not intended to be exhaustive and, among other considerations, does not describe state, local or international tax consequences.

      The 2005 Employee Stock Purchase Plan is intended to qualify as an “employee stock purchase plan” under Section 423 of the Code. Participant contributions to the 2005 Employee Stock Purchase Plan are made on an after-tax basis. That is, a participant’s contributions are deducted from compensation that is taxable to the participant and for which the Company is generally entitled to a tax deduction.

      Generally, no taxable income is recognized by a participant with respect to either the grant or exercise of his or her option under the 2005 Employee Stock Purchase Plan. The Company will have no tax deduction with respect to either of those events. A participant will generally recognize income (or loss) only upon a sale or disposition of any shares that the participant acquires under the 2005 Employee Stock Purchase Plan. The particular tax consequences of a sale of shares acquired under the 2005 Employee Stock Purchase Plan depend on whether the participant has held the shares for a “Required Holding Period” before selling or disposing of the shares. The Required Holding Period starts on the date that the participant acquires the shares under the 2005 Employee Stock Purchase Plan and ends on the later of (1) two years after the Enrollment Date of the Offering Period in which the participant acquired the shares, or (2) one year after the Exercise Date on which the participant acquired the shares.

      If the participant holds the shares for the Required Holding Period and then sells the shares at a price in excess of the purchase price paid for the shares, the gain on the sale of the shares will be taxed as ordinary income to the participant to the extent of the lesser of (1) the amount by which the fair market value of the shares on the Enrollment Date of the Offering Period in which the participant acquired the shares exceeded the option price of the shares, or (2) the gain on the sale of the shares. Any portion of the participant’s gain on the sale of the shares not taxed as ordinary income will be taxed as long-term capital gain. If the participant holds the shares for the Required Holding Period and then sells the shares at a price less than the purchase price paid for the shares, the loss on the sale will be treated as a long-term capital loss to the participant. The Company will not be entitled to a tax deduction with respect to any shares held by the participant for the Required Holding Period, regardless of whether the shares are eventually sold at a gain or a loss.

      The participant has a “Disqualifying Disposition” if the participant disposes of the shares before the participant has held the shares for the Required Holding Period. If the participant sells the shares in a Disqualifying Disposition, the participant will realize ordinary income in an amount equal to the difference between the fair market value of the shares on the Exercise Date on which the participant acquired the shares and the purchase price paid for the shares, and the Company generally will be entitled to a corresponding tax deduction. In addition, if the participant makes a Disqualifying Disposition of the shares at a price in excess of the fair market value of the shares on the Exercise Date, the participant will realize capital gain in an amount equal to the difference between the selling price of the shares and the fair market value of the shares on the Exercise Date. Alternatively, if the participant makes a Disqualifying Disposition of the shares at a price less than the fair market value of the shares on the Exercise Date, the participant will realize a capital loss in an amount equal to the difference between the fair market value of the shares on the Exercise Date and the selling price of the shares. The Company will not be entitled to a tax deduction with respect to any capital gain realized by the participant.

Specific Benefits

      The benefits that will be received by or allocated to eligible employees under the 2005 Employee Stock Purchase Plan cannot be determined at this time because the amount of contributions set aside to purchase shares of the Company’s common stock under the 2005 Employee Stock Purchase Plan (subject to the limitations discussed above) is entirely within the discretion of each participant.

      The closing price of a share of the Company’s common stock as of September 20, 2005 was $12.90 per share.

Vote Required and Recommendation of the Board of Directors

      The affirmative vote of a majority of the shares of the Company’s common stock represented in person or by proxy at the Annual Meeting and entitled to vote (which shares must also constitute at least the required quorum) is required for approval of the 2005 Employee Stock Purchase Plan. If you are a beneficial owner, please note that brokers, trustees and other nominees do not have discretionary authority to vote on your behalf for the adoption of the 2005 Employee Stock Purchase Plan. As a result, if you do not submit voting instructions to your broker, trustee or other nominee, your shares will not be considered entitled to vote for purposes of determining whether Proposal 2 has been approved by shareholders and, therefore, will not be

counted in determining the outcome of Proposal 2. If you abstain from voting on Proposal 2, whether you are a shareholder of record or a beneficial owner, your vote will have the effect of a vote “against” approval of the 2005 Employee Stock Purchase Plan.

      The Board of Directors believes that adoption of the 2005 Employee Stock Purchase Plan will promote the interests of the Company and its shareholders and continue to enable the Company to attract, retain and award persons important to its success.

      THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” PROPOSAL 2 TO APPROVE THE 2005 EMPLOYEE STOCK PURCHASE PLAN AS DESCRIBED ABOVE AND SET FORTH IN EXHIBIT B HERETO.

      Members of the Board of Directors who are also employees or officers of the Company are eligible to participate in the 2005 Employee Stock Purchase Plan and thus have a personal interest in the approval of the 2005 Employee Stock Purchase Plan.

PROPOSAL 3

APPROVAL OF AMENDMENT TO THE

WESTERN DIGITAL CORPORATION

2004 PERFORMANCE INCENTIVE PLAN

General

      At the Annual Meeting, shareholders will be asked to approve an amendment to the Western Digital Corporation 2004 Performance Incentive Plan, which would increase the number of shares of the Company’s common stock available for award grants under the 2004 Performance Incentive Plan by an additional 13,000,000 shares. This amendment was adopted, subject to shareholder approval, by the Board of Directors on September 22, 2005.

      As of September 22, 2005, a total of 5,226,498 shares of the Company’s common stock were subject to outstanding awards granted under the 2004 Performance Incentive Plan (assuming a maximum payout of 300% of the target number of performance shares awarded under the 2004 Performance Incentive Plan), and an additional 2,164,502 shares of the Company’s common stock were available for new award grants under the 2004 Performance Incentive Plan. The Board of Directors approved the additional share authority requested under the 2004 Performance Incentive Plan based, in part, on a belief that the number of shares currently available under the 2004 Performance Incentive Plan does not give the Company sufficient flexibility to adequately provide for future incentives. The Company will continue to have the authority to grant awards under the 2004 Performance Incentive Plan, within the existing 2004 Performance Incentive Plan limits, if shareholders do not approve this 2004 Performance Incentive Plan proposal.

Summary Description of the 2004 Performance Incentive Plan

      The principal terms of the 2004 Performance Incentive Plan are summarized below. The following summary is qualified in its entirety by the full text of the 2004 Performance Incentive Plan (as proposed to be amended), which has been filed as Exhibit C to the copy of this Proxy Statement that was filed electronically with the Securities and Exchange Commission and can be reviewed on the Securities and Exchange Commission’s website at www.sec.gov or on our website at www.westerndigital.com. A copy of the 2004 Performance Incentive Plan document may also be obtained without charge by writing the Company’s Secretary at Western Digital Corporation, 20511 Lake Forest Drive, Lake Forest, California 92630-7741.

      Purpose. The purpose of the 2004 Performance Incentive Plan is to promote the success of the Company and the interests of the Company’s shareholders by providing an additional means for the Company to attract, motivate, retain and reward directors, officers, employees and other eligible persons through the grant of awards and incentives for high levels of individual performance and improved financial performance of the Company. Equity-based awards are also intended to further align the interests of award recipients and the Company’s shareholders.

      Administration. The Board of Directors or one or more committees appointed by the Board of Directors administers the 2004 Performance Incentive Plan. To the extent required by any applicable listing agency, the 2004 Performance Incentive Plan must be administered by a committee composed entirely of independent directors (within the meaning of the applicable listing agency). The Board of Directors has delegated general administrative authority for the 2004 Performance Incentive Plan to the Compensation Committee. A committee may delegate some or all of its authority with respect to the 2004 Performance Incentive Plan to another committee of directors, and certain limited authority to grant awards to employees may be delegated to one or more officers of the Company. (The appropriate acting body, be it the Board of Directors, a committee within its delegated authority, or an officer within his or her delegated authority, is referred to in this proposal as the “Administrator”).

      The Administrator has broad authority under the 2004 Performance Incentive Plan with respect to awarding grants including, without limitation, the authority:

      No Repricing. In no case (except due to an adjustment to reflect a stock split or similar event or any repricing that may be approved by shareholders) will any adjustment be made to a stock option or stock appreciation right award under the 2004 Performance Incentive Plan (by amendment, cancellation and regrant, exchange or other means) that would constitute a repricing of the per share exercise or base price of the award.

      Eligibility. Persons eligible to receive awards under the 2004 Performance Incentive Plan include officers or employees of the Company or any of its subsidiaries, directors of the Company, and certain consultants and advisors to the Company or any of its subsidiaries. As of July 1, 2005, approximately 23,161 officers and employees of the Company and its subsidiaries (including all of the Named Executive Officers), and each of the Company’s non-employee directors, are considered eligible under the 2004 Performance Incentive Plan.

      Authorized Shares; Limits on Awards. As of September 22, 2005, the maximum number of shares of the Company’s common stock that may be issued or transferred pursuant to awards under the 2004 Performance Incentive Plan equaled the sum of: (1) 8,520,684 shares, plus (2) the number of any shares subject to stock options granted under the Company’s Employee Stock Option Plan, Stock Option Plan for Non-Employee Directors or Broad-Based Stock Incentive Plan (collectively, the “Existing Plans”) which expire, or for any reason are cancelled or terminated, after that date without being exercised, plus (3) the number of any shares of restricted stock granted under the Broad-Based Stock Incentive Plan that were unvested as of that date and are forfeited, terminated, cancelled or otherwise reacquired by the Company without having become vested. As of September 22, 2005, 16,634,794 options and 267,206 shares of unvested restricted stock were subject to awards then outstanding under the Existing Plans. If shareholders approve this proposal, the number of shares available for award grant purposes under the 2004 Performance Incentive Plan will be increased by an additional 13,000,000 shares.

      Shares issued in respect of any “full-value award” granted under the 2004 Performance Incentive Plan will be counted against the share limit described in the preceding paragraph as 1.35 shares for every one share actually issued in connection with the award. For example, if a stock bonus of 100 shares of the Company’s common stock were granted under the 2004 Performance Incentive Plan, 135 shares would be charged against the share limit with respect to that stock bonus award. For this purpose, a “full-value award” generally means any award granted under the plan other than: (1) shares delivered in respect of compensation earned but deferred, and (2) shares delivered pursuant to option or stock appreciation right grants the per share exercise

or base price, as applicable, of which is at least equal to the fair market value of a share of the Company’s common stock at the time of grant of the award.

      The following other limits are also contained in the 2004 Performance Incentive Plan:

      To the extent that an award is settled in cash or a form other than shares, the shares that would have been delivered had there been no such cash or other settlement will not be counted against the shares available for issuance under the 2004 Performance Incentive Plan. In the event that shares are delivered in respect of a dividend equivalent right, only the actual number of shares delivered with respect to the award shall be counted against the share limits of the 2004 Performance Incentive Plan. To the extent that shares are delivered pursuant to the exercise of a stock appreciation right or stock option, the number of underlying shares as to which the exercise related shall be counted against the applicable share limits, as opposed to only counting the shares actually issued. (For purposes of clarity, if a stock appreciation right relates to 100,000 shares and is exercised at a time when the payment due to the participant is 15,000 shares, 100,000 shares shall be charged against the applicable share limits with respect to such exercise.) Shares that are subject to or underlie awards which expire or for any reason are cancelled or terminated, are forfeited, fail to vest, or for any reason are not paid or delivered under the 2004 Performance Incentive Plan will again be available for subsequent awards under the 2004 Performance Incentive Plan. In addition, the 2004 Performance Incentive Plan generally provides that shares issued in connection with awards that are granted by or become obligations of the Company through the assumption of awards (or in substitution for awards) in connection with an acquisition of another company will not count against the shares available for issuance under the 2004 Performance Incentive Plan.

      Types of Awards. The 2004 Performance Incentive Plan authorizes stock options, stock appreciation rights, restricted stock, stock bonuses and other forms of awards granted or denominated in the Company’s common stock or units of the Company’s common stock, as well as cash bonus awards pursuant to Section 5.2 of the 2004 Performance Incentive Plan. The 2004 Performance Incentive Plan retains flexibility to offer competitive incentives and to tailor benefits to specific needs and circumstances. Any award may be paid or settled in cash.

      A stock option is the right to purchase shares of the Company’s common stock at a future date at a specified price per share (the “exercise price”). The per share exercise price of an option generally may not be less than the fair market value of a share of the Company’s common stock on the date of grant. The maximum term of an option is ten years from the date of grant. An option may either be an incentive stock option or a nonqualified stock option. Incentive stock option benefits are taxed differently from nonqualified stock options, as described under “Federal Income Tax Consequences of Awards Under the 2004 Performance Incentive Plan” below. Incentive stock options are also subject to more restrictive terms and are limited in amount by the U.S. Internal Revenue Code and the 2004 Performance Incentive Plan. Incentive stock options may only be granted to employees of the Company or a subsidiary.

      A stock appreciation right is the right to receive payment of an amount equal to the excess of the fair market value of a share of the Company’s common stock on the date of exercise of the stock appreciation right

over the base price of the stock appreciation right. The base price will be established by the Administrator at the time of grant of the stock appreciation right and generally cannot be less than the fair market value of a share of the Company’s common stock on the date of grant. Stock appreciation rights may be granted in connection with other awards or independently. The maximum term of a stock appreciation right is ten years from the date of grant.

      The per share exercise price of an option or the per share base price of a stock appreciation right may, however, be less than the fair market value of a share of the Company’s common stock on the date of grant in the case of (1) awards granted as a substitution for another award, or (2) if the option or stock appreciation right will be counted as a “full-value award” against the plan’s share limit (as described above under “Authorized Shares; Limits on Awards”).

      The other types of awards that may be granted under the 2004 Performance Incentive Plan include, without limitation, stock bonuses, restricted stock, performance stock, stock units, dividend equivalents, or similar rights to purchase or acquire shares, and cash awards granted consistent with Section 5.2 of the 2004 Performance Incentive Plan as described below.

      The 2004 Performance Incentive Plan generally imposes a minimum one-year vesting requirement on any full-value awards that are subject to a performance-based vesting condition and generally requires that any other full-value awards not vest more rapidly than in monthly installments over a three-year period, although the Administrator may provide for accelerated vesting of awards under certain specified circumstances such as a change of control of the Company or a termination of the award holder’s employment (other than for cause). In addition, the portion of any “full-value awards” under the 2004 Performance Incentive Plan that do not meet these vesting requirements are subject to the 5% limit described above under “Authorized Shares; Limits on Awards.”

      Performance-Based Awards. The Administrator may grant awards that are intended to be performance-based awards within the meaning of Section 162(m) of the U.S. Internal Revenue Code. Performance-based awards are in addition to any of the other types of awards that may be granted under the 2004 Performance Incentive Plan (including options and stock appreciation rights which may also qualify as performance-based awards for Section 162(m) purposes). Performance-based awards may be in the form of restricted stock, performance stock, stock units, other rights, or cash bonus opportunities.

      The vesting or payment of performance-based awards (other than options or stock appreciation rights) will depend on the absolute or relative performance of the Company on a consolidated, subsidiary, segment, division, or business unit basis. The Administrator will establish the criterion or criteria and target(s) on which performance will be measured. The Administrator must establish criteria and targets in advance of applicable deadlines under the U.S. Internal Revenue Code and while the attainment of the performance targets remains substantially uncertain. The criteria that the Administrator may use for this purpose will include one or more of the following: earnings per share, cash flow (which means cash and cash equivalents derived from either net cash flow from operations or net cash flow from operations, financing and investing activities), total shareholder return, gross revenue, revenue growth, operating income (before or after taxes), net earnings (before or after interest, taxes, depreciation and/or amortization), return on equity or on assets or on net investment, cost containment or reduction, or any combination thereof. The performance measurement period with respect to an award may range from three months to ten years. Performance targets will be adjusted to mitigate the unbudgeted impact of material, unusual or nonrecurring gains and losses, accounting changes or other extraordinary events not foreseen at the time the targets were set unless the Administrator provides otherwise at the time of establishing the targets.

      Performance-based awards may be paid in stock or in cash (in either case, subject to the limits described under the heading “Authorized Shares; Limits on Awards” above). Before any performance-based award (other than an option or stock appreciation right) is paid, the Administrator must certify that the performance target or targets have been satisfied. The Administrator has discretion to determine the performance target or targets and any other restrictions or other limitations of performance-based awards and may reserve discretion to reduce payments below maximum award limits.

      Deferrals. The Administrator may provide for the deferred payment of awards, and may determine the other terms applicable to deferrals. The Administrator may provide that deferred settlements include the payment or crediting of interest or other earnings on the deferred amounts, or the payment or crediting of dividend equivalents where the deferred amounts are denominated in shares.

      Acceleration of Awards; Possible Early Termination of Awards. Generally, and subject to limited exceptions set forth in the 2004 Performance Incentive Plan, if any person acquires more than 33¹/3% of the outstanding common stock or combined voting power of the Company, if certain changes in a majority of the Board of Directors occur over a period of not longer than two years, if shareholders prior to a transaction do not continue to own more than 50% of the voting securities of the Company (or a successor or a parent) following a reorganization, merger, statutory share exchange or consolidation or similar corporate transaction involving the Company or any of its subsidiaries, a sale or other disposition of all or substantially all of the Company’s assets or the acquisition of assets or stock of another entity by the Company or any of its subsidiaries, or if the Company is dissolved or liquidated, then awards then-outstanding under the 2004 Performance Incentive Plan may become fully vested or paid, as applicable, and may terminate or be terminated in such circumstances. The Administrator also has the discretion to establish other change in control provisions with respect to awards granted under the 2004 Performance Incentive Plan. For example, the Administrator could provide for the acceleration of vesting or payment of an award in connection with a change in control event that is not described above and provide that any such acceleration shall be automatic upon the occurrence of any such event.

      Transfer Restrictions. Subject to certain exceptions contained in Section 5.7 of the 2004 Performance Incentive Plan, awards under the 2004 Performance Incentive Plan generally are not transferable by the recipient other than by will or the laws of descent and distribution and are generally exercisable, during the recipient’s lifetime, only by the recipient. Any amounts payable or shares issuable pursuant to an award generally will be paid only to the recipient or the recipient’s beneficiary or representative. The Administrator has discretion, however, to establish written conditions and procedures for the transfer of awards to other persons or entities, provided that such transfers are made for estate or tax planning or charitable purposes for no (or nominal) consideration and comply with applicable federal and state securities laws.

      Adjustments. As is customary in incentive plans of this nature, each share limit and the number and kind of shares available under the 2004 Performance Incentive Plan and any outstanding awards, as well as the exercise or purchase prices of awards, and performance targets under certain types of performance-based awards, are subject to adjustment in the event of certain reorganizations, mergers, combinations, recapitalizations, stock splits, stock dividends, or other similar events that change the number or kind of shares outstanding, and extraordinary dividends or distributions of property to the shareholders.

      No Limit on Other Authority. The 2004 Performance Incentive Plan does not limit the authority of the Board of Directors or any committee to grant awards or authorize any other compensation, with or without reference to the Company’s common stock, under any other plan or authority.

      Termination of or Changes to the 2004 Performance Incentive Plan. The Board of Directors may amend or terminate the 2004 Performance Incentive Plan at any time and in any manner. Shareholder approval for an amendment will be required only to the extent then required by applicable law, to the extent required under Sections 162, 422 or 424 of the U.S. Internal Revenue Code to preserve the intended tax consequences of the plan, or to the extent the amendment constitutes a “material revision” of the plan within the meaning of applicable listing rules. Shareholder approval will be required for any amendment that proposes to increase the maximum number of shares that may be delivered with respect to awards granted under the 2004 Performance Incentive Plan or to increase any other share limit set forth in the plan. (Adjustments as a result of stock splits or similar events will not, however, be considered an amendment requiring shareholder approval.) Unless terminated earlier by the Board of Directors, the authority to grant new awards under the 2004 Performance Incentive Plan will terminate on September 21, 2014. Outstanding awards, as well as the Administrator’s authority with respect thereto, generally will continue following the expiration or termination of the plan. Generally speaking, outstanding awards may be amended by the Administrator (except for a repricing), but

the consent of the award holder is required if the amendment (or any plan amendment) materially and adversely affects the holder.

Federal Income Tax Consequences of Awards under the 2004 Performance Incentive Plan

      The U.S. federal income tax consequences of the 2004 Performance Incentive Plan under current federal law, which is subject to change, are summarized in the following discussion of the general tax principles applicable to the 2004 Performance Incentive Plan. This summary is not intended to be exhaustive and, among other considerations, does not describe state, local, or international tax consequences.

      With respect to nonqualified stock options, the Company is generally entitled to deduct and the participant recognizes taxable income in an amount equal to the difference between the option exercise price and the fair market value of the shares at the time of exercise. With respect to incentive stock options, the Company is generally not entitled to a deduction nor does the participant recognize income at the time of exercise, although the participant may be subject to the U.S. federal alternative minimum tax.

      The current federal income tax consequences of other awards authorized under the 2004 Performance Incentive Plan generally follow certain basic patterns: stock appreciation rights are taxed and deductible in substantially the same manner as nonqualified stock options; nontransferable restricted stock subject to a substantial risk of forfeiture results in income recognition equal to the excess of the fair market value over the price paid (if any) only at the time the restrictions lapse (unless the recipient elects to accelerate recognition as of the date of grant); bonuses, cash and stock-based performance awards, dividend equivalents, stock units, and other types of awards are generally subject to tax at the time of payment; and compensation otherwise effectively deferred is taxed when paid. In each of the foregoing cases, the Company will generally have a corresponding deduction at the time the participant recognizes income.

      If an award is accelerated under the 2004 Performance Incentive Plan in connection with a “change in control” (as this term is used under the U.S. Internal Revenue Code), the Company may not be permitted to deduct the portion of the compensation attributable to the acceleration (“parachute payments”) if it exceeds certain threshold limits under the U.S. Internal Revenue Code (and certain related excise taxes may be triggered). Furthermore, the aggregate compensation in excess of $1,000,000 attributable to awards that are not “performance-based” within the meaning of Section 162(m) of the U.S. Internal Revenue Code may not be permitted to be deducted by the Company in certain circumstances.

Specific Benefits under the 2004 Performance Incentive Plan

      The Company has not approved any other awards that are conditioned upon shareholder approval of the proposed amendment of the 2004 Performance Incentive Plan. The number, amount and type of awards to be received by or allocated to eligible persons in the future under the 2004 Performance Incentive Plan cannot be determined at this time. If the share increase reflected in this 2004 Performance Incentive Plan proposal had been in effect in fiscal 2004, the Company expects that its award grants for fiscal 2004 would not have been substantially different from those actually made in that year under the 2004 Performance Incentive Plan.

      For information regarding stock-based awards granted to the Named Executive Officers during fiscal 2004, see the material under the heading “Executive Compensation” above. For information regarding past award grants under the 2004 Performance Incentive Plan, see the “Aggregate Past Grants under the 2004 Performance Incentive Plan” table below.

      The closing market price for a share of the Company’s common stock as of September 22, 2005 was $12.77 per share.

Aggregate Past Grants Under the 2004 Performance Incentive Plan

      As of September 22, 2005, awards covering 5,545,807 shares of the Company’s common stock had been granted under the 2004 Performance Incentive Plan. The following table shows information regarding the distribution of those awards among the persons and groups identified below, option exercises and restricted stock vesting prior to and option and unvested restricted stock holdings as of that date.

Vote Required and Recommendation of the Board of Directors

      The affirmative vote of a majority of the shares of the Company’s common stock represented in person or by proxy at the Annual Meeting and entitled to vote (which shares must also constitute at least the required quorum) is required for approval of the amendment to the 2004 Performance Incentive Plan. If you are a beneficial owner, please note that brokers, trustees and other nominees do not have discretionary authority to vote on your behalf for the approval of the 2004 Performance Incentive Plan proposal. As a result, if you do not submit voting instructions to your broker, trustee or other nominee, your shares will not be considered entitled to vote for purposes of determining whether Proposal 3 has been approved by shareholders and, therefore, will not be counted in determining the outcome of Proposal 3. If you abstain from voting on Proposal 3, whether you are a shareholder of record or a beneficial owner, your vote will have the effect of a vote “against” approval of the 2004 Performance Incentive Plan proposal.

      The Board of Directors believes that the proposed amendment to the 2004 Performance Incentive Plan will promote the interests of the Company and its shareholders and will help the Company and its subsidiaries continue to be able to attract, retain and reward persons important to the Company’s success.

      THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” PROPOSAL 3 TO APPROVE THE AMENDMENT TO THE 2004 PERFORMANCE INCENTIVE PLAN AS DESCRIBED ABOVE.

      All members of the Board of Directors are eligible for awards under the 2004 Performance Incentive Plan and thus have a personal interest in the approval of the amendment to the 2004 Performance Incentive Plan.

EQUITY COMPENSATION PLAN INFORMATION

      The following table gives information with respect to the Company’s equity compensation plans as of July 1, 2005, which plans were as follows: Non-Employee Directors Stock-for-Fees Plan, 2004 Performance Incentive Plan, Employee Stock Option Plan, Broad-Based Stock Incentive Plan, Stock Option Plan for Non-Employee Directors and 1993 Employee Stock Purchase Plan. With the exception of the Broad-Based Stock Incentive Plan, these plans have each been approved by the Company’s shareholders. Following expiration of the Employee Stock Option Plan on November 10, 2004 and approval of the 2004 Performance Incentive Plan by the Company’s shareholders on November 18, 2004, no new awards are permitted under the Employee Stock Option Plan, the Broad-Based Stock Incentive Plan or the Stock Option Plan for Non-Employee Directors. In addition, if shareholders approve the Company’s 2005 Employee Stock Purchase Plan as described in Proposal 2, the Company’s 1993 Employee Stock Purchase Plan will immediately terminate and no shares will be available for future issuance under that plan.

      The following table does not reflect the additional shares that will be available under the 2005 Employee Stock Purchase Plan if Proposal 2 is approved by shareholders or the additional shares that will be available under the 2004 Performance Incentive Plan if Proposal 3 is approved by shareholders.

Broad-Based Stock Incentive Plan

      On September 30, 1999, the Company’s Board of Directors approved the Broad-Based Stock Incentive Plan under which options to purchase 4,799,700 shares of the Company’s common stock were outstanding as of July 1, 2005 and 314,609 shares of restricted stock remained unvested as of July 1, 2005. This plan was

intended to qualify as “broadly-based” under the New York Stock Exchange shareholder approval policy at the time of its adoption and was not submitted to the Company’s shareholders for approval. Following approval of the Company’s 2004 Performance Incentive Plan by the Company’s shareholders in November 2004, no new awards are permitted under the Broad-Based Incentive Plan after such date and, therefore, no shares remain available for grant under the plan.

      The stock options that remain outstanding under the plan are not incentive stock options under Section 422 of the Internal Revenue Code. The purchase price per share of common stock subject to each such option granted under the plan is equal to or exceeds 100% of the fair market value of such common stock on the date of grant, and the term of each outstanding option granted under the plan will not exceed ten years from the date of its grant. The shares of restricted common stock that were awarded under the plan and remain unvested are all subject to time-based vesting requirements. All of such shares of restricted stock will vest on or before September 21, 2008 unless such shares are earlier forfeited as required by the plan or by an agreement evidencing the award made under the plan.

      The Broad-Based Stock Incentive Plan is administered by the Compensation Committee of the Board of Directors. The committee has broad discretionary authority to construe and interpret the plan. The committee may in its discretion provide financing to a participant in a principal amount sufficient to pay the purchase price of any award and/or to pay the amount of taxes required by law to be withheld with respect to any award. Any such loan shall be subject to all applicable legal requirements and restrictions pertinent thereto. Further, the committee may, through the terms of the award or otherwise, provide for lapse of restrictions on an option or restricted stock, either immediately upon a change of control of the Company (as defined in the plan), or upon termination of the eligible employee’s employment within 24 months following a change of control. The committee may also provide for the exercise, payment or lapse of restrictions on an award that is only effective if no provision is made in the change of control transaction.

      Agreements evidencing an award made under the plan may be amended, altered or discontinued by the Board or the Compensation Committee, subject to rules of the New York Stock Exchange requiring shareholder approval. These amendments may include: (i) reducing the exercise price of outstanding options; or (ii) after the date of a change of control, impairing the rights of any award holder, without such holder’s consent, under any award granted prior to the date of any change of control. No award, or any interest in an award may be transferred in any manner, other than by will or the laws of descent and distribution, unless the agreement evidencing an award expressly states that it is transferable.

AUDIT COMMITTEE

      The following is the report of the Audit Committee of the Company with respect to the Company’s audited financial statements for the fiscal year ended July 1, 2005. This report shall not be deemed soliciting material or to be filed with the Securities and Exchange Commission or subject to Regulation 14A or 14C under the Securities Exchange Act or to the liabilities of Section 18 of the Securities Exchange Act, nor shall any information in this report be incorporated by reference into any past or future filing under the Securities Act or the Securities Exchange Act, except to the extent the Company specifically requests that it be treated as soliciting material or specifically incorporates it by reference into a filing under the Securities Act or the Securities Exchange Act.

Report of the Audit Committee

      The Audit Committee represents the Board in discharging its responsibilities relating to the accounting, reporting, and financial practices of the Company and its subsidiaries, and has general responsibility for oversight and review of the accounting and financial reporting practices, internal controls and accounting and audit activities of the Company and its subsidiaries. The Audit Committee acts pursuant to a written charter. The Audit Committee Charter was originally adopted by the Board of Directors on September 6, 1995 and was most recently amended on March 16, 2005. A copy of the amended charter is attached as Exhibit A to this Proxy Statement and is also available on the Company’s website under the Governance section at www.westerndigital.com. The Board of Directors has determined that each of the members of the Audit Committee qualifies as an “independent” director under applicable rules of the New York Stock Exchange and the Securities and Exchange Commission.

      Management is responsible for the preparation, presentation and integrity of the Company’s financial statements, the financial reporting process, accounting principles and internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. The Company’s independent accountants are responsible for performing an independent audit of the financial statements in accordance with auditing standards generally accepted in the United States of America and issuing a report thereon. The Audit Committee’s responsibility is to monitor and oversee these processes. The members of the Audit Committee are not professionally engaged in the practice of accounting or auditing. The Audit Committee relies, without independent verification, on the information provided to it and on the representations made by management and the independent accountants that the financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP).

      During fiscal 2005, the Audit Committee met a total of fourteen times, six in person and eight via telephone conference. During fiscal 2005, the Audit Committee also met and held discussions with management and KPMG LLP, the Company’s independent accountants. The meetings were conducted so as to encourage communication among the members of the Audit Committee, management and the independent accountants. The Audit Committee has discussed with KPMG LLP the matters required to be discussed by Statement on Auditing Standards No. 61 (Communication with Audit Committees) relating to the conduct of the audit.

      The Audit Committee reviewed and discussed the audited financial statements of the Company for the fiscal year ended July 1, 2005 with management and the independent accountants. The Board of Directors, including the Audit Committee, received an opinion of KPMG LLP as to the conformity of such audited consolidated financial statements with GAAP.

      The Audit Committee discussed with KPMG LLP the overall scope and plan for its audit. The Audit Committee met regularly with KPMG LLP, with and without management present, to discuss the results of its examination, its evaluation of the Company’s internal control over financial reporting and the overall quality of the Company’s accounting principles. In addition, the Audit Committee has received written disclosures and a letter from KPMG LLP regarding its independence from the Company as required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees) and has discussed with KPMG LLP the independence of that firm. The Audit Committee also reviewed, among other things, the amount of fees paid to KPMG LLP for audit and non-audit services.

      Based upon such reviews and discussions, the Audit Committee has recommended to the Board of Directors of the Company that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended July 1, 2005, for filing with the Securities and Exchange Commission. The Audit Committee also appointed KPMG LLP to serve as the Company’s independent accountants for the fiscal year ending June 30, 2006.

PROPOSAL 4

RATIFICATION OF APPOINTMENT OF INDEPENDENT PUBLIC ACCOUNTANTS

      The accounting firm of KPMG LLP, certified public accountants, has served the Company as its independent accountants since its incorporation in 1970. The Audit Committee of the Board of Directors has again appointed KPMG to serve as the Company’s independent accountants for the fiscal year ending June 30, 2006. The appointment of KPMG is not required to be submitted for shareholder approval, but the Board of Directors has elected to seek ratification of the appointment of the independent accountants by the affirmative vote of a majority of the shares represented in person or by proxy and entitled to vote at the Annual Meeting. If a majority of the shares represented and entitled to vote do not ratify this appointment, the Audit Committee will reconsider its appointment of KPMG and will either continue to retain this firm or appoint new independent accountants. One or more representatives of KPMG are expected to be present at the Annual Meeting and will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

      Following are the fees paid by the Company to KPMG for the fiscal years ended July 1, 2005 and July 2, 2004:

      The Audit Committee has adopted a policy regarding the pre-approval of audit and non-audit services to be provided by the Company’s independent accountants. The policy provides that KPMG LLP is required to seek pre-approval by the Audit Committee of all audit and permissible non-audit services by providing a description of the services to be performed and specific fee estimates for each such service. The Audit Committee has delegated to the Chairman of the Audit Committee the authority to pre-approve audit-related and permissible non-audit services and associated fees up to a maximum for any one audit-related or non-audit service of US$50,000, provided that the Chairman shall report any decisions to pre-approve such audit-related or non-audit services and fees to the full Audit Committee at its next regular meeting for ratification. One-hundred percent (100%) of the Audit-Related Fees and Tax Fees billed by KPMG during fiscal 2004 and fiscal 2005 were approved by the Audit Committee pursuant to regulations of the Securities and Exchange Commission.

Vote Required and Recommendation of the Board of Directors

      The affirmative vote of a majority of the shares of the Company’s common stock represented in person or by proxy at the Annual Meeting and entitled to vote (which shares must also constitute at least the required quorum) is required for ratification of the appointment of KPMG LLP as the Company’s independent accountants for the fiscal year ending June 30, 2006.

      THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” PROPOSAL 4 TO RATIFY THE APPOINTMENT OF KPMG LLP AS THE INDEPENDENT ACCOUNTANTS OF THE COMPANY FOR THE FISCAL YEAR ENDING JUNE 30, 2006.

VOTING VIA THE INTERNET OR BY TELEPHONE

      Shareholders may submit proxies by mail, telephone or the Internet.

Shareholders of record may submit proxies telephonically by calling 1 (800) 690-6903 (within the U.S. and Canada only, toll-free) and following the recorded instructions. Shareholders of record may submit a proxy via the Internet by going to the website at www.proxyvote.com and following the instructions to obtain your records and to create an electronic voting instruction form. Beneficial shareholders who hold their shares in “street name” may vote by telephone or by Internet by following the instructions specified on the voting instruction cards provided by their broker, trustee or nominee.

If you submit your proxy or voting instruction by telephone or Internet there is no need to return the enclosed proxy card or voting instruction card.

The granting of proxies electronically is permitted by Section 212(c)(2) of the Delaware General Corporation Law.

If and to the extent that any right to purchase reserved shares shall not be exercised by any Participant for any reason or if such right to purchase shall terminate as provided herein, shares that have not been so purchased hereunder shall again become available for the purposes of the Plan unless the Plan shall have been terminated, but all shares sold under the Plan, regardless of source, shall be counted against the limitation set forth above.

      (b) From time to time and without shareholder approval, the Committee may fix a maximum limit on the number of shares that may be acquired by any individual during an Exercise Period under the Plan, which limit shall be effective no earlier than the first Offering Period that commences after the determination of such limit by the Committee; provided, however, that any adjustment to such limit pursuant to Section 15 shall apply to any Exercise Period in progress at the time such adjustment is made.

      4.     Administration of the Plan.

      (a) The Plan shall be administered by a Committee appointed by, and which shall serve at the pleasure of, the Board. The Committee shall consist of two or more directors, each of whom is a “Non-Employee Director” within the meaning of Rule 16b-3 promulgated under the Securities Exchange Act of 1934, as amended, as such rule may be amended from time to time. The Committee shall have authority to interpret the Plan, to prescribe, amend and rescind rules and regulations relating to the Plan, and to make all other determinations necessary or advisable for the administration of the Plan, all of which actions and determinations shall be final, conclusive and binding on all persons.

      (b) The Committee may request advice or assistance or employ such other persons as it in its absolute discretion deems necessary or appropriate for the proper administration of the Plan, including, but not limited to employing a brokerage firm, bank or other financial institution to assist in the purchase of shares, delivery of reports or other administrative aspects of the Plan.

      (c) Neither the Board nor any Committee, nor any member thereof or person acting at the direction thereof, shall be liable for any act, omission, interpretation, construction or determination made in good faith in connection with the Plan, and all such persons shall be entitled to indemnification and reimbursement by the Company in respect of any claim, loss, damage or expense (including, without limitation, attorneys’ fees) arising or resulting therefrom to the fullest extent permitted by law and/or under any directors and officers liability insurance coverage that may be in effect from time to time.

      5.     Eligibility to Participate in the Plan.

      Subject to limitations imposed by Section 423(b) of the Code, any Eligible Employee who is employed by the Company or a Participating Subsidiary on an Enrollment Date shall be eligible to participate in the Plan for the Offering Period beginning on that Enrollment Date.

      6.     Offering Periods.

      During the term of the Plan, the Company will grant options to purchase shares of Common Stock in each Offering Period to all Participants in that Offering Period. The Committee shall determine from time to time, subject to the requirements of Section 423 of the Code and no later than the first Offering Period to commence under the Plan, when Offering Periods will be offered during the term of the Plan and shall establish the Enrollment Date(s), the number and duration of the Exercise Period(s), and the Exercise Date(s) for such Offering Period(s), which determinations shall be effective no later than the first Offering

Period that commences after they are made by the Committee and provided, however, that no Offering Period may exceed twenty-four (24) months in duration. To the extent consistent with Section 423 of the Code, the Committee may provide for a new Offering Period to commence prior to the termination of one or more preceding Offering Periods.

      7.     Election to Participate in the Plan.

      (a) Each Eligible Employee may elect to participate in an Offering Period by completing an enrollment agreement on a form approved by and in a manner prescribed by the Committee (or its delegate) or, if the Committee does not require enrollment forms, by otherwise completing such enrollment procedures as the Committee may prescribe. Such agreement must be filed with the Company or such other procedures must be completed, as applicable, prior to the applicable Enrollment Date, unless the Committee establishes an earlier deadline for filing the enrollment form for all Eligible Employees with respect to a given Offering Period. An Eligible Employee may participate in an Offering Period only if, as of the Enrollment Date of such Offering Period, such Eligible Employee is not participating in any prior Offering Period which is continuing at the time of such proposed enrollment.

      (b) Payroll deductions for a Participant shall commence on the first payroll date on or following the Enrollment Date and shall end on the last payroll date in the Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in Section 12.

      (c) Unless a Participant elects otherwise prior to the Enrollment Date of the immediately succeeding Offering Period, an Eligible Employee who is participating in an Offering Period as of the last Exercise Date of such Offering Period (the “Prior Offering Period”) shall be deemed (i) to have elected to participate in the immediately succeeding Offering Period and (ii) to have authorized the same payroll deduction for such immediately succeeding Offering Period as was in effect for such Participant immediately prior to the expiration or termination of the Prior Offering Period.

      (d) In its discretion, the Committee may determine (with such determination to be effective no earlier than the first Offering Period that commences after such determination by the Committee) that the participation of all Participants on an Exercise Date in an Offering Period that includes more than one Exercise Period shall terminate and such Participants shall be enrolled in a new Offering Period commencing immediately following such Exercise Date if, during such Offering Period, the Fair Market Value determined as of such Exercise Date within such Offering Period is lower than the Fair Market Value determined as of the Enrollment Date of such Offering Period. In such event, each of such Participants shall be deemed for purposes of this Plan (i) to have elected to participate in such new Offering Period, and (ii) to have authorized the same payroll deduction for such new Offering Period as was in effect for such Participant immediately prior to the Termination Date.

      8.     Payroll Deductions.

      (a) All Participant contributions to the Plan shall be made only by payroll deductions. At the time a Participant files the enrollment agreement with respect to an Offering Period, the Participant shall authorize payroll deductions to be made on each payroll date during the Offering Period in an amount up to 10% (or such other limit as the Committee may establish prior to the start of the applicable Offering Period) of the Eligible Compensation which the Participant receives on each payroll date during such Offering Period. The Committee also may prescribe other limits, rules or procedures for payroll deductions. Unless otherwise provided by the Committee, the amount of such payroll deductions shall be a whole percentage (i.e., 1%, 2%, 3%, etc.) of the Participant’s Eligible Compensation.

      (b) All payroll deductions made for a Participant shall be deposited in the Company’s general corporate account and shall be credited to the Participant’s account under the Plan. No interest shall accrue or be credited with respect to the payroll deductions of a Participant under the Plan. A Participant may not make any additional payments into such account. All payroll deductions received or held by the Company under the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions.

      (c) A Participant may discontinue participation in the Plan as provided in Section 12. Unless otherwise provided by the Committee in advance of an Offering Period, a Participant may at any time during the Offering Period (but no more than four times in any calendar year) reduce or increase (subject to the limitations of Section 8(a) above) the rate of his or her payroll deductions by completing and filing with the Company a change notice in the form provided by the Company. Any such reduction in the rate of a Participant’s payroll deductions shall be effective as of the pay period specified by the Participant in the Participant’s change notice, but in no event sooner than the first pay period ending more than fifteen (15) days after the Participant files the change notice with the Company. Any such increase in the rate of a Participant’s payroll deductions shall be effective as of the first date of the next Exercise Period within such Offering Period.

      9.     Grant of Options.

      (a) On the Enrollment Date of each Offering Period, subject to the limitations set forth in Sections 3, 9(b) and 17 hereof, each Participant shall be granted an option to purchase on each Exercise Date during such Offering Period up to a number of shares of the Common Stock determined by dividing such Participant’s payroll deductions accumulated during the Exercise Period ending on such Exercise Date by the Exercise Price for such Exercise Period (determined as provided in Section 10 below), provided that the number of shares subject to the option shall not exceed five (5) times the number of shares determined by dividing (i) 10% (or such other maximum limit on a Participant’s payroll deductions for the Offering Period as the Committee may establish pursuant to Section 8(a)) of the Participant’s Eligible Compensation over the Offering Period (determined based upon the Participant’s rate of Eligible Compensation in effect as of the Enrollment Date), by (ii) the Fair Market Value of a share of the Common Stock on the Enrollment Date multiplied by the percentage (not less than 85%) used to calculate the Exercise Price for that Offering Period.

      (b) Notwithstanding any provision of the Plan to the contrary, no Participant shall be granted an option under the Plan (i) if, immediately after the grant, such Participant (or any other person whose stock would be attributed to such Participant pursuant to Section 424(d) of the Code) would own stock and/or hold outstanding options to purchase stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company or of any Parent or any Subsidiary of the Company, or (ii) which permits such Participant’s rights to purchase stock under all employee stock purchase plans of the Company, its Subsidiaries and any Parent to accrue at a rate which exceeds $25,000 of fair market value of such stock (determined at the time such option is granted) for each calendar year in which such option is outstanding at any time.

      10.     Exercise Price.

      The Committee shall establish from time to time (but no later than the first Offering Period to commence under the Plan) the method for determining the Exercise Price for each Offering Period under the Plan in accordance with this Section 10, which determination shall be effective no earlier than the first Offering Period that commences after such determination is made by the Committee. In making its determination, the Committee may provide that the Exercise Price for an Offering Period shall be determined by applying a discount amount (not to exceed 15%) to either (1) the Fair Market Value of a share of Common Stock on the Enrollment Date of such Offering Period, or (2) the Fair Market Value of a share of Common Stock on the applicable Exercise Date, or (3) the lesser of the Fair Market Value of a share on the Enrollment Date of such Offering Period or the Fair Market Value of a share on the applicable Exercise Date. Notwithstanding anything to the contrary in the preceding provisions of this Section 10, in no event shall the Exercise Price per share be less than the par value of a share of Common Stock.

      11.     Exercise of Options.

      Unless a Participant withdraws from the Plan as provided in Section 12, the Participant’s option for the purchase of shares will be exercised automatically on each Exercise Date of the Offering Period, and the maximum number of full shares subject to option will be purchased for the Participant at the applicable Exercise Price with the accumulated payroll deductions in the Participant’s account. Any amount remaining in the Participant’s account after an Exercise Date that is not sufficient to purchase a whole share shall be held

in the account until the next Exercise Date in such Offering Period, unless the Offering Period has been over-subscribed or has terminated with such Exercise Date, in which event (or in the event any other applicable Plan limit has been exceeded by that Participant in that Offering Period) such amount shall be refunded to the Participant.

      12.     Withdrawal; Termination of Employment.

      (a) A Participant may withdraw all but not less than all of the payroll deductions credited to the Participant’s account under the Plan at any time by giving written notice to the Company. All of the Participant’s payroll deductions credited to the Participant’s account will be paid to him or her promptly after receipt of the Participant’s notice of withdrawal, the Participant’s participation in the Plan will be automatically terminated, and no further payroll deductions for the purchase of shares will be made. Payroll deductions will not resume on behalf of a Participant who has withdrawn from the Plan unless written notice is delivered to the Company within the open enrollment period preceding the commencement of an Exercise Period directing the Company to resume payroll deductions.

      (b) Upon termination of the Participant’s Continuous Employment prior to the Exercise Date of an Offering Period for any reason, including retirement or death, the payroll deductions credited to the Participant’s account will be returned to the Participant or, in the case of death, to the Participant’s estate, and the Participant’s options to purchase shares under the Plan will be automatically terminated.

      (c) In the event a Participant fails to maintain Continuous Employment for at least twenty (20) hours per week during an Offering Period, the Participant will be deemed to have elected to withdraw from the Plan, the payroll deductions credited to the Participant’s account will be returned to the Participant, and the Participant’s options to purchase shares under the Plan will be terminated.

      (d) A Participant’s withdrawal from an Offering Period will not have any effect upon the Participant’s eligibility to participate in a succeeding Offering Period or in any similar plan which may hereafter be adopted by the Company.

      13.     Transferability.

      Neither payroll deductions credited to a Participant’s account nor options to purchase Common Stock granted under the Plan may be transferred, assigned, pledged or otherwise disposed of by a Participant other than by will or the laws of descent and distribution. Options granted under the Plan are exercisable during a Participant’s lifetime only by the Participant.

      14.     Reports.

      Individual accounts will be maintained for each Participant in the Plan. Statements of account will be given to Participants promptly following each Exercise Date, which statements will set forth the amounts of payroll deductions, the per share purchase price, the number of shares purchased and the remaining cash balance, if any.

      15.     Adjustments Upon Changes in Capitalization.

      (a) If the outstanding shares of Common Stock are increased or decreased, or are changed into or are exchanged for a different number or kind of shares, as a result of one or more reorganizations, restructurings, recapitalizations, reclassifications, stock splits, reverse stock splits, stock dividends or any similar unusual or extraordinary corporate transaction, appropriate adjustment shall be made in the number and/or kind of shares, and the Exercise Price thereof, which may be issued in the aggregate and to any Participant upon exercise of options granted under the Plan.

      (b) In the event of the proposed dissolution or liquidation of the Company, each Offering Period then in progress will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Committee. In the event of a proposed sale of all or substantially all of the assets of the Company, or the merger of the Company with or into another corporation or entity, each option under the Plan shall be assumed or an equivalent option shall be substituted by such successor corporation or entity or a parent or subsidiary of such successor corporation or entity, unless the Committee determines, in the exercise

of its sole discretion and in lieu of such assumption or substitution, that the Participants shall have the right to exercise the option as to all of the optioned stock. If the Committee makes an option fully exercisable under these circumstances in lieu of assumption or substitution, each Offering Period then in progress shall be shortened and a new Exercise Date shall be set (the “New Exercise Date”), as of which date any Offering Period then in progress will terminate. The New Exercise Date shall be on or before the date of consummation of the transaction and the Committee shall notify each participant in writing, at least ten (10) days prior to the New Exercise Date, that the Exercise Date for his or her option has been changed to the New Exercise Date and that his or her option will be exercised automatically on the New Exercise Date, unless prior to such date he or she has withdrawn from the Offering Period as provided in Section 12. The Exercise Price on the New Exercise Date shall be determined as provided in Section 10 hereof, and for purposes of determining such Exercise Price, the New Exercise Date shall be treated as the “Exercise Date.”

      (c) In all cases, the Committee shall have full discretion to exercise any of the powers and authority provided under this Section 15, and the Committee’s actions hereunder shall be final and binding on all Participants. No fractional shares of stock shall be issued under the Plan pursuant to any adjustment authorized under the provisions of this Section 15.

      16.     Amendment of the Plan.

      The Board may at any time, or from time to time, amend or suspend the Plan, in whole or in part and without notice; provided, however, that the Plan may not be amended in any way that will cause rights issued under the Plan to fail to meet the requirements for employee stock purchase plans as defined in Section 423 of the Code or any successor thereto, including, without limitation, shareholder approval if required. No options may be granted during any suspension of the Plan or after a termination of the Plan pursuant to Section 17(b) below, but the Committee will retain jurisdiction as to options then outstanding in accordance with the terms of the Plan. No amendment, suspension or termination pursuant to this Section 16 or Section 17 shall, without written consent of the Participant, affect in any manner materially adverse to the Participant any right or benefits of such Participant or obligations of the Company under any option granted under the Plan prior to the effective date of such change; provided that the Board may amend, suspend or terminate the Plan as to any outstanding options granted under the Plan for an Offering Period, effective as of any Exercise Date within that Offering Period, without the consent of the Participants to whom such options were granted. In no event shall changes contemplated by Section 7(d) or Section 15 be deemed to constitute changes or amendments requiring Participant consent.

      17.     Termination of the Plan.

      The Plan and all rights of Employees hereunder shall terminate:

      In the event that the Plan terminates under circumstances described in Section 17(a) above, reserved shares remaining as of the termination date shall be sold to Participants on a pro rata basis.

      18.     Notices.

      All notices or other communications by a Participant to the Company under or in connection with the Plan shall be deemed to have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.

      19.     Shareholder Approval.

      Continuance of the Plan shall be subject to approval by the shareholders of the Company within twelve months before or after the date the Plan is adopted. If such shareholder approval is obtained at a duly held shareholders’ meeting, it may be obtained by the affirmative vote of the holders of a majority of the outstanding shares of the Company present or represented and entitled to vote thereon.

      20.     Conditions Upon Issuance of Shares.

      (a) The Plan, the grant and exercise of options to purchase shares of Common Stock under the Plan, and the Company’s obligation to sell and deliver shares upon the exercise of options to purchase shares shall be subject to all applicable federal, state and foreign laws, rules and regulations, and to such approvals by any regulatory or governmental agency as may, in the opinion of counsel for the Company, be required.

      (b) The Company may make such provisions as it deems appropriate for withholding by the Company pursuant to federal or state income tax laws of such amounts as the Company determines it is required to withhold in connection with the purchase or sale by a Participant of any Common Stock acquired pursuant to the Plan. The Company may require a Participant to satisfy any relevant tax requirements before authorizing any issuance of Common Stock to such Participant.

      21.     Employees’ Rights.

      (a) Nothing in the Plan (or in any other document related to the Plan) will confer upon any Eligible Employee or Participant any right to continue in the employ or other service of the Company or any Subsidiary, constitute any contract or agreement of employment or other service or affect an employee’s status as an employee at will, nor shall interfere in any way with the right of the Company or any Subsidiary to change such person’s compensation or other benefits or to terminate his or her employment or other service, with or without cause. Nothing contained in this Section 21(a), however, is intended to adversely affect any express independent right of any such person under a separate employment or service contract.

      (b) No Participant or other person will have any right, title or interest in any fund or in any specific asset (including shares of Common Stock) of the Company or any Subsidiary by reason of any option hereunder. Neither the provisions of the Plan (or of any other document related to the Plan), nor the creation or adoption of the Plan, nor any action taken pursuant to the provisions of the Plan will create, or be construed to create, a trust of any kind or a fiduciary relationship between the Company or any Subsidiary and any Participant or other person. To the extent that a Participant or other person acquires a right to receive payment pursuant to the Plan, such right will be no greater than the right of any unsecured general creditor of the Company.

      (c) A Participant will not be entitled to any privilege of stock ownership as to any shares of Common Stock not actually delivered to and held of record by the Participant. No adjustment will be made for dividends or other rights as a shareholder for which a record date is prior to such date of delivery.

      22.     Miscellaneous.

      (a) The Plan, the options granted hereunder and any other documents related to the Plan shall be governed by, and construed in accordance with, the laws of the State of Delaware.

      (b) If any provision of the Plan shall be held by a court of competent jurisdiction to be invalid and unenforceable, the remaining provisions of the Plan shall continue in effect.

      (c) Captions and headings are given to the sections of the Plan solely as a convenience to facilitate reference. Such captions and headings shall not be deemed in any way material or relevant to the construction of interpretation of the Plan or any provision hereof.

      (d) The adoption of the Plan shall not affect any other Company or Subsidiary compensation or incentive plans in effect. Nothing in the Plan will limit or be deemed to limit the authority of the Board or Committee (1) to establish any other forms of incentives or compensation for employees of the Company or any Subsidiary (with or without reference to the Common Stock), or (2) to grant or assume options (outside the scope of and in addition to those contemplated by the Plan) in connection with any proper corporate purpose; to the extent consistent with any other plan or authority. Benefits received by a Participant under an option granted pursuant to the Plan shall not be deemed a part of the Participant’s compensation for purposes of the determination of benefits under any other employee welfare or benefit plans or arrangements, if any, provided by the Company or any Subsidiary, except where the Committee or the Board (or the Board of Directors of the Subsidiary that sponsors such plan or arrangement, as applicable) expressly otherwise provides or authorizes in writing.
